The Prospect Park Zoo is located in Brooklyn, New York. It is part of the Wildlife Conservation Society, which partnered with the New York Department of Parks and Recreation in the 1980s to create a zoo that mimicked the natural habitats of its animals. Groundbreaking on the zoo began in 1987, and it was opened to the public in 1993. It contains over 400 animals representing more than 100 species.

The zoo is part of the Wildlife Conservation Society’s network of animal parks in New York City. The others include the Bronx Zoo, the Central Park Zoo, the New York Aquarium, and the Queens Zoo. It offers programs for kids and families, including a Girl Scouts program, summer camp, and a Discovery Center where children can interact with and learn about the zoo’s animals.

The lyrics, "It's round on the end and "Hi" in the Middle," "O-HI-O!" comes from a 1922 Broadway musical, The Hotel Mouse. The story is about a girl who tells riddles; one of the songs, Round on the End, High in the Middle, is a riddle that refers to the state of Ohio. In 1940, the Ohio State University Marching Band played Round on the End, High in the Middle for the first time; and by the 1950s, it would be part of the band's field formation. In 1977, Devo, a band from Akron, Ohio, featured a similar lyric in their song Jocko Homo. They sing, "I got a rhyme that comes in a riddle." "O-Hi-O!" "What's round on the end and high in the middle?" "O-Hi-O!"

Residents refer to Sault Sainte Marie, Michigan as “The Soo,” and a city with the same name lies across the St. Marys River in Canada. “Sault” is an old French word for rapids, while “Sainte Marie” honors the Virgin Mary. The city has passed from the French, to the British, and finally to the Americans. In the present day, Sault Sainte Marie relies largely on river shipping and tourism. Boats navigate the rapids through a series of locks, which alter water levels to allow ships to pass. Visitors come for outdoor activities like fishing, watersports, and hiking, and also to see attractions like the Soo Locks Park and other parks, museums, and historical buildings.

From 1791 to 1841, “Upper Canada” referred to the region that would become modern-day Ontario, Canada. Under British rule, the province was created in 1791 by splitting Quebec into Lower Canada and Upper Canada. However, the two Canadas were eventually reunited as the Province of Canada. Upper Canada Village is a reconstruction of an 1860s English Canadian village, created in 1961. Over forty historical buildings were moved to the location from historical sites before the St. Lawrence Seaway project flooded the so-called “lost villages.” The site has mills, workshops, farms, and homes where reenactors practice period crafts, grow vegetables, and raise livestock. The village is near the site of the War of 1812’s Battle of Crysler’s Farm, where Canadian and British forces turned back an attempted American invasion of Montreal.

Once producing over half the dinnerware sold in the United States, East Liverpool, Ohio is also referred to by such nicknames as "Crockery City" and "The Pottery Capital of the World". The amount of ceramics manufacturers has since dwindled down to a few in this historic town but accordingly, the city is now home to The Museum of Ceramics which was established in 1980 by the Ohio History Connection. The museum's collection is housed within the city's former U.S. Post Office -- the 1906 Beaux Arts style building whose intricate facade is featured on this button. It boasts a large assemblage of pottery and dinnerware, manufacturer histories, life-size dioramas, as well as an extensive archive of documents and photographs on the subject of ceramics. It is also known as the home of the women's pottery group, "The Lady Slippers" -- named for the "slip", or watered-down clay, utilized in pottery-making.

With less than 20,000 residents, Trenton is a small community located in Ontario, Canada. It was originally settled in 1784 by French colonists and named after the nearby Trent River, which took its name from the River Trent in England. The name “Trent” is suspected to be a Romano-British word meaning “severely flooded.” From early on, Trenton was populated by workers from the lumber industry and was well liked for its convenient port location. The town was home to a large munitions plant during the First World War, but the factory was leveled by a massive explosion three weeks before the Armistice. Notable people from the town include Henry Comstock, the owner of the Nevada mine where the Comstock Lode was discovered, and Marc Tessier-Lavigne, the current president of Stanford University.

LACAC, an acronym for the Local Architectural Conservation Advisory Committee, is a government-created entity that is responsible for recommending heritage property in Canada. The committee was established with the 1974 passage of the Ontario Heritage Act, and its members are devoted to preserving historical sites throughout the province. Examples of conserved landmarks that are protected by LACAC are the Clock Tower, Trent Port Historical Museum, and Fraser Park Gates—all of which are situated in downtown Trenton. Interestingly, the Fraser Park Gates were built after World War I using funds raised by a Canadian women’s organization. Names of Trenton soldiers lost in both World Wars are etched in the monument.

In 1980, Ketchum Advertising introduced the tagline “You’ve Got a Friend in Pennsylvania” on television, radio, print, and billboard ads throughout the state of Pennsylvania. From 1980-1988, the phrase also appeared on the state’s license plates.

A grammatical controversy surrounded the phrase during its use, most notably between columnist James Kilpatrick and then-Governor Richard Thornburgh. The issue focused on the use of “you have” alongside “got.” Some felt placing  “you have” next to “got” was grammatically incorrect, therefore the phrase should have read “You have a friend in Pennsylvania.”

Indianapolis is the state capital of Indiana and the largest city in the state with a population of 863,002.  It is home to the world-famous Indianapolis 500, the Indianapolis Colts football team, and Indiana Pacers basketball team.  The name Indianapolis is a combination of Indiana meaning “Indian Land” and polis, which is the Greek word for city.  Indiana gained statehood in 1816 and adopted “The Crossroads of America” as the official state motto in 1937 since 4 major interstate highways connect in the state.  The Chamber of Commerce Building was built in 1926 and stands to this day.

Roton Point is an area of Norfolk, Connecticut that has been a place to go for relaxation for almost 150 years. In 1880, the area became popular for its amusement park and the big bands of the era that performed there. After the amusement park was torn down in 1941, Roton Point became a family beach club that marketed a “casually elegant” location for summer activities.
