Kume no Heinai-dō: Kume no Heinai-dō (久米平内堂 ) is a small folk shrine located in Asakusa in Taitō, Tokyo.  The shrine houses a stone statue of Kume no Heinai, a samurai from the early Edo period (17th century).  According to the Asakusa tourism bureau, there are few facts about the life of Kume no Heinai, but he is said to have died in 1683.  Oral tradition holds that Heinai excelled in Kenjutsu, the martial art of swordsmanship, killing many people over the years.  In the latter half of his life, he is said to have lived in the Sensō-ji temple in Asakusa where he devoted himself to Zen-Buddhism and held religious services in honor of the people he killed.  Shortly before his death he ordered his followers to carve his likeness on a stone and bury it near the Niōmon – the entrance to the Buddhist temple and a busy district in the city.  His wish was to have his statue be stepped on by as many people as possible in order to expiate the crimes he committed in life.  The statue was eventually retrieved and is now stored inside the shrine itself.  It is because of this that the shrine initially carried the name "Fumitsuke" (踏みつけ ) , which means "to tread on", but over time the meaning was lost and the shrine's name came to be spelled 文付け, which means "love letter".  Both words are pronounced "Fumitsuke" and the shrine is now worshipped by the general public as a deity of marriage and match-making.  Kume no Heinai-dō was destroyed in March 1945 during World War II.  The current temple was rebuilt in October 1978.

Pen Mar, Maryland: Pen Mar is an unincorporated community in Washington County, Maryland, and Franklin County, Pennsylvania, United States.  It is one of the border towns in the United States with a portmanteau name.  Pen Mar came to prominence in the 20th century due to the construction of Pen Mar Park by the Western Maryland Railroad.  The construction of the Pen Mar resort caused the area to become a destination for many people.  While the resort has long been dismantled, the area still has some significance in Maryland, since it is the northern starting point for the Maryland section of the Appalachian Trail.

Federal Music Project: The Federal Music Project (FMP), part of the Federal government of the United States New Deal program Federal Project Number One, employed musicians, conductors and composers during the Great Depression.  In addition to performing thousands of concerts, offering music classes, organizing the Composers Forum Laboratory, hosting music festivals and creating 34 new orchestras, employees of the FMP researched American traditional music and folk songs, a practice now called ethnomusicology.  In the latter domain the Federal Music Project did notable studies on cowboy, Creole, and what was then termed Negro music.  During the Great Depression, many people visited these symphonies to forget about the economic hardship of the time.  In 1939, the FMP transitioned to the Works Progress Administration's Music Program, which along with many other WPA projects, was phased out in the midst of World War II.

Sexuality after spinal cord injury: Although spinal cord injury (SCI) often causes sexual dysfunction, many people with SCI are able to have satisfying sex lives.  Physical limitations acquired from SCI affect sexual function and sexuality in broader areas, which in turn has important effects on quality of life.  Damage to the spinal cord impairs its ability to transmit messages between the brain and parts of the body below the level of the lesion.  This results in lost or reduced sensation and muscle motion, and affects orgasm, erection, ejaculation, and vaginal lubrication.  More indirect causes of sexual dysfunction include pain, weakness, and side effects of medications.  Psycho-social causes include depression and altered self-image.  Many people with SCI have satisfying sex lives, and many experience sexual arousal and orgasm.  People with SCI employ a variety of adaptations to help carry on their sex lives healthily, by focusing on different areas of the body and types of sexual acts.  Neural plasticity may account for increases in sensitivity in parts of the body that have not lost sensation, so people often find newly sensitive erotic areas of the skin in erogenous zones or near borders between areas of preserved and lost sensation.

Allegany Ballistics Laboratory: Allegany Ballistics Laboratory (ABL) located in Rocket Center, West Virginia, is a diverse industrial complex employing some 1,000 people across 1628 acre .  The facility is a member of the Federal Laboratory Consortium and is operated by Alliant Techsystems (ATK) under contract with the Naval Sea Systems Command (NAVSEA).

2002 El Ayyat railway accident: The El Ayyat train disaster happened at 02:00 on the morning of 20 February 2002 in an eleven-carriage passenger train travelling from Cairo to Luxor.  A cooking gas cylinder exploded in the fifth carriage, creating a fire which engulfed seven third-class carriages, reducing them almost to cinders.  The initial number of dead given by officials at the time was 383, all Egyptians.  However, considering that seven carriages were burnt to the ground, and each carriage was packed with at least double the maximum carrying capacity of 150, this number is considered by many people to be a great underestimate.  The dubious nature of the given death toll lies with the absence of a full passenger list; accounting for those missing was almost impossible at the time.  In addition, the fire was so intense and the carriages so badly burned that many corpses had been reduced to ash.  As there was no means of communication between the driver and the rear carriages, the driver did not know of the fire until about two hours after it had begun, resulting in many people, attempting to flee from the overcrowded carriages, jumping to their death.  Some important Egyptians have commentated that the official number of 383 dead is grossly inaccurate and was an attempt to lessen the damage done to the reputation of the government.  Many people consider a number of about 1000 deaths to be more accurate.

McKenzie, Maryland: McKenzie is an unincorporated community in Allegany County, Maryland, containing only a few houses, and mostly land.  Its name is derived from a family which owned a large farm along the river bottom in the area.  It is directly across from the Allegany Ballistics Laboratory in Rocket Center, West Virginia.  The area used to be a railroad junction of the Patterson Creek Cutoff and the main B&O line.  McKenzie is also the site of one of the first settlements in Allegany county, where many pieces of glass, metal, stone, and some coin have been found.  In the fields of the river bottom, arrowheads and flint can be found, suggesting a possible Native American community at one time, similar to the Barton, Maryland site.

William Leonard Pickard: William Leonard Pickard (born October 21, 1945 in DeKalb County, Georgia) is one of two people convicted in the largest lysergic acid diethylamide (LSD) manufacturing case in history.  In 2000, while moving their LSD laboratory across Kansas, Pickard and Clyde Apperson were pulled over while driving a Ryder rental truck and a follow car.  The laboratory had been stored near a renovated Atlas-E missile silo near Wamego, Kansas but the two men had never actually produced LSD there.  One of the men intimately involved in the case but not charged due to his cooperation, Gordon Todd Skinner, owned the property where the laboratory equipment was stored.

Niles Canyon ghost: The Niles Canyon ghost story is the Northern California variation on the vanishing hitchhiker archetype.  There are many different variations of this story depending on whom you ask.  All stories include a girl being involved in some sort of motorized vehicle accident on February 26 (year often changed).  One variation of the story includes a girl being involved in a car crash on Niles Canyon road (off the 680 freeway in Sunol, California) on the way to her prom.  The girl died on impact and to this day is said to haunt Niles Canyon road every February 26.  The tale of the haunting goes that people traveling along Niles Canyon road (now Highway 84) on the night of February 26 will see a normal-looking high school-aged girl walking along the road in a prom dress (many people have said it is white).  People traveling along the road (mostly those traveling alone) have said to have stopped and offered the girl a ride.  She accepts the ride, giving the driver an address across the bridge (either Dumbarton or Bay Bridge depending on the storyteller).  Once the driver gets to the beginning of the bridge, the girl will disappear.  Sometimes people have gone to the address to find that a girl many years ago matching that description once lived there.  Today, many people will travel along this treacherous pitch black road in the hopes of catching a glimpse of the Niles Canyon ghost.

Drug corridor: Drug corridor is the name given to various paths in the U.S., generally being coterminal with major highways and interstates, that are major highways for the flow of illicit drugs into, out of, and across the U.S.  There is no definitive drug corridor, as many people claim that their city lies in a drug corridor (just as many people claim that their city is the "meth capital of the world").  Many sources, however, corroborate that the main arteries of drug flow are east–west across the U.S., North from Mexico, and South from Canada.  Most of the marijuana and cocaine imported into the U.S. flows from Latin America across the U.S.–Mexican border, while many imported synthetic drugs and former designer drugs flow south from Canada.
