Passage: Camp Chase was an American Civil War training and prison camp established in May 1861, on land leased by the U.S. Government. It replaced the much smaller Camp Jackson which was established by Ohio Governor William Dennison Jr as a place for Ohio's union volunteers to meet. It originally operated from a city park. The main entrance was on the National Road west of Downtown Columbus, Ohio. Boundaries of the camp were present-day Broad Street (north), Hague Avenue (east), Sullivant Avenue (south), and near Westgate Avenue (west). Named for former Ohio Governor, Salmon P. Chase, who was Lincoln's Secretary of the Treasury; it was a training camp for Ohio volunteer army soldiers, a parole camp, a muster outpost, and later a prisoner-of-war camp. The nearby Camp Thomas served as a similar base for the Regular Army. As many as 150,000 Union soldiers and 25,000 Confederate prisoners passed through its gates from 18611865. By February 1865, over 9,400 men were held at the prison. More than 2,200 Confederates are buried in the Camp Chase Cemetery. Western Virginia and Kentucky civilians suspected of actively supporting secession, including former three-term United States Congressman Richard Henry Stanton were held at the facility. The prison camp also held Confederates captured during Morgan's Raid in 1863, including Col. Basil W. Duke.

Passage: Medieval Krakow was surrounded by a 1.9 mile (3km) defensive wall complete with 46 towers and seven main entrances leading through them. The fortifications around the Old Town were erected over the course of two centuries. The current architectural plan of Stare Miastothe 13th-century merchants' townwas drawn up following the Tatar invasions of 1259 and 1287. It features the centrally located Rynek Gowny, or Main Square, the largest medieval town square of any European city. There is a number of historic landmarks in its vicinity, such as St. Mary's Basilica (Koscio Mariacki), Church of St. Wojciech (St. Adalbert's), Church of St. Barbara, as well as other national treasures. At the center of the plaza, surrounded by kamienice (row houses) and noble residences, stands the Renaissance cloth hall Sukiennice (currently housing gift shops, restaurants and merchant stalls) with the National Gallery of Art upstairs.

Passage: In most cases, Tony Hulman would give the command, then ride in the pace car during the pace laps. Mary F. Hulman would give the command near the pace car, but rarely rode in the pace car due to her age and declining health. Eventually, the location was moved to near the start/finish line, and in 2001, it was moved to the new Victory Podium stage adjacent to the Pagoda. In 2011 only, Mari George moved back to the front of the starting grid to give the command, and then she rode in the pace car with A. J. Foyt. In 2014, as a special gesture to Jim Nabors's final performance at Indy, the starting command was given in unison by both Mari George and Nabors, marking the first time a non-member of the Hulman-George family had given the command for the 500 since 1954. In 2016 for the 100th Indianapolis 500, now-matriarch Mari was joined by three subsequent generations of the Hulman-George family, who gave the command together. Due to her advanced age, the 2016 race would be Mari's final turn giving the command. Later that same year, Tony George gave the starting command for the Brickyard 400, his first time giving a command since a restart command in 1986. For the 2017 Indianapolis 500, the duty was permanently assigned to Tony George. In that year, Tony George began using the phrase "Drivers, start your engines" instead of the more familiar "Lady and gentlemen..." variation. However, for the 2019 race, George recited that latter variation.
