Document 5: Ann Arbor, Michigan: Ann Arbor's residential neighborhoods contain architectural styles ranging from classic 19th-century and early-20th-century designs to ranch-style houses. Among these homes are a number of kit houses built in the early 20th century. Contemporary-style houses are farther from the downtown district. Surrounding the University of Michigan campus are houses and apartment complexes occupied primarily by student renters. Tower Plaza, a 26-story condominium building located between the University of Michigan campus and downtown, is the tallest building in Ann Arbor. The 19th-century buildings and streetscape of the Old West Side neighborhood have been preserved virtually intact; in 1972, the district was listed on the National Register of Historic Places, and it is further protected by city ordinances and a nonprofit preservation group.
Document 6: Ann Arbor, Michigan: Borders Books, started in Ann Arbor, was opened by brothers Tom and Louis Borders in 1971 with a stock of used books. The Borders chain was based in the city, as was its flagship store until it closed in September 2011. Domino's Pizza's headquarters is near Ann Arbor on Domino's Farms, a 271-acre (110 ha) Frank Lloyd Wright-inspired complex just northeast of the city. Another Ann Arbor-based company is Zingerman's Delicatessen, which serves sandwiches and has developed businesses under a variety of brand names. Zingerman's has grown into a family of companies which offers a variety of products (bake shop, mail order, creamery, coffee) and services (business education).

Document 7: Fast food restaurant: Some historians concur that A&W, which opened in 1919 and began franchising in 1921, was the first fast food restaurant (E. Tavares). Thus, the American company White Castle is generally credited with opening the second fast - food outlet in Wichita, Kansas in 1921, selling hamburgers for five cents apiece from its inception and spawning numerous competitors and emulators. What is certain, however, is that White Castle made the first significant effort to standardize the food production in, look of, and operation of fast - food hamburger restaurants. William Ingram's and Walter Anderson's White Castle System created the first fast food supply chain to provide meat, buns, paper goods, and other supplies to their restaurants, pioneered the concept of the multi-state hamburger restaurant chain, standardized the look and construction of the restaurants themselves, and even developed a construction division that manufactured and built the chain's prefabricated restaurant buildings. The McDonald's Speedee Service System and, much later, Ray Kroc's McDonald's outlets and Hamburger University all built on principles, systems and practices that White Castle had already established between 1923 and 1932.
Document 8: Ann Arbor, Michigan: A person from Ann Arbor is called an "Ann Arborite", and many long-time residents call themselves "townies". The city itself is often called "A²" ("A-squared") or "A2" ("A two") or "AA", "The Deuce" (mainly by Chicagoans), and "Tree Town". With tongue-in-cheek reference to the city's liberal political leanings, some occasionally refer to Ann Arbor as "The People's Republic of Ann Arbor" or "25 square miles surrounded by reality", the latter phrase being adapted from Wisconsin Governor Lee Dreyfus's description of Madison, Wisconsin. In A Prairie Home Companion broadcast from Ann Arbor, Garrison Keillor described Ann Arbor as "a city where people discuss socialism, but only in the fanciest restaurants." Ann Arbor sometimes appears on citation indexes as an author, instead of a location, often with the academic degree MI, a misunderstanding of the abbreviation for Michigan. Ann Arbor has become increasingly gentrified in recent years.
Document 9: Ann Arbor, Michigan: Since the university's establishment in the city in 1837, the histories of the University of Michigan and Ann Arbor have been closely linked. The town became a regional transportation hub in 1839 with the arrival of the Michigan Central Railroad, and a north—south railway connecting Ann Arbor to Toledo and other markets to the south was established in 1878. Throughout the 1840s and the 1850s settlers continued to come to Ann Arbor. While the earlier settlers were primarily of British ancestry, the newer settlers also consisted of Germans, Irish, and African-Americans. In 1851, Ann Arbor was chartered as a city, though the city showed a drop in population during the Depression of 1873. It was not until the early 1880s that Ann Arbor again saw robust growth, with new immigrants coming from Greece, Italy, Russia, and Poland. Ann Arbor saw increased growth in manufacturing, particularly in milling. Ann Arbor's Jewish community also grew after the turn of the 20th century, and its first and oldest synagogue, Beth Israel Congregation, was established in 1916.
Document 10: Ann Arbor, Michigan: Ann Arbor has a long history of openness to marijuana, given Ann Arbor's decriminalization of cannabis, the large number of medical marijuana dispensaries in the city (one dispensary, called People's Co-op, was directly across the street from Michigan Stadium until zoning forced it to move one mile to the west), the large number of pro-marijuana residents, and the annual Hash Bash: an event that is held on the first Saturday of April. Until (at least) the successful passage of Michigan's medical marijuana law, the event had arguably strayed from its initial intent, although for years, a number of attendees have received serious legal responses due to marijuana use on University of Michigan property, which does not fall under the City's progressive and compassionate ticketing program.

Document 12: Ann Arbor, Michigan: Ann Arbor was founded in 1824, named for wives of the village's founders and the stands of Bur Oak trees. The University of Michigan moved from Detroit to Ann Arbor in 1837, and the city grew at a rapid rate in the early to mid-20th century. During the 1960s and 1970s, the city gained a reputation as a center for left-wing politics. Ann Arbor became a focal point for political activism and served as a hub for the civil-rights movement and anti-Vietnam War movement, as well as various student movements.
Document 13: Jim's Restaurants: Jim's Restaurants is an American chain of restaurants owned by Uptown San Antonio, Texas-based Frontier Enterprises. Jim's, most well known for its breakfast and charbroiled Frontier Burgers, was started in 1947 when founder G. Jim Hasslocher built his first burger stand. The burger stand grew and became a drive-in burger concept with carhops, which eventually led to full-service restaurants in several locations. Prior to 1980, the restaurant chain expanded into the Houston metro area until Frontier withdrew and sold off the Houston locations. As of April 2010, Frontier operates 16 locations in the San Antonio area and 3 in Austin.
Document 14: Ann Arbor, Michigan: During the 1960s and 1970s, the city gained a reputation as an important center for liberal politics. Ann Arbor also became a locus for left-wing activism and served as a hub for the civil-rights movement and anti-Vietnam War movement, as well as the student movement. The first major meetings of the national left-wing campus group Students for a Democratic Society took place in Ann Arbor in 1960; in 1965, the city was home to the first U.S. teach-in against the Vietnam War. During the ensuing 15 years, many countercultural and New Left enterprises sprang up and developed large constituencies within the city. These influences washed into municipal politics during the early and mid-1970s when three members of the Human Rights Party (HRP) won city council seats on the strength of the student vote. During their time on the council, HRP representatives fought for measures including pioneering antidiscrimination ordinances, measures decriminalizing marijuana possession, and a rent-control ordinance; many of these remain in effect in modified form. Alongside these liberal and left-wing efforts, a small group of conservative institutions were born in Ann Arbor. These include Word of God (established in 1967), a charismatic inter-denominational movement; and the Thomas More Law Center (established in 1999), a religious-conservative advocacy group.
Document 15: Ann Arbor, Michigan: Ann Arbor's "Tree Town" nickname stems from the dense forestation of its parks and residential areas. The city contains more than 50,000 trees along its streets and an equal number in parks. In recent years, the emerald ash borer has destroyed many of the city's approximately 10,500 ash trees. The city contains 157 municipal parks ranging from small neighborhood green spots to large recreation areas. Several large city parks and a university park border sections of the Huron River. Fuller Recreation Area, near the University Hospital complex, contains sports fields, pedestrian and bike paths, and swimming pools. The Nichols Arboretum, owned by the University of Michigan, is a 123-acre (50 ha) arboretum that contains hundreds of plant and tree species. It is on the city's east side, near the university's Central Campus. Located across the Huron River just beyond the university's North Campus is the university's Matthaei Botanical Gardens, which contains 300 acres of gardens and a large tropical conservatory.
