Arlington is a city in Texas, west of Dallas. It's home to the University of Texas at Arlington (UTA), whose campus has a modern planetarium. In River Legacy Parks, trails cut through hardwood forest rich in wildlife. The park also has the River Legacy Living Science Center, with aquariums, terrariums and interactive exhibits. The Dallas Cowboys football team plays at AT&T Stadium, which also hosts concerts.
By 1925 the city's population was estimated at 3,031—well under the population of Dallas and Fort Worth at the time. In 1929, a horse-racing track called Arlington Downs was constructed by W.T. Waggoner close by to the speakeasy. Gambling was still illegal, but people were making bets regardless. Waggoner and his sons campaigned to make parimutuel betting legal, and in 1933 the state issued its first legal gambling permit to Arlington Downs. The track was immensely profitable at that point, making a daily average of $113,000 before inflation with a daily attendance average of 6,700 people. At the end of the 1937 season, the state legislature repealed their parimutuel gambling laws, and the Downs were sold to commercial developers.
In the 1940s, the Arlington Downs was used as a rodeo and event venue. Top O' Hill Terrace evaded the police until 1947, when famous Texas Ranger M. T. "Lone Wolf" Gonzaullas caught the gambling operation in full-swing and had the place shut down. The 1940s brought World War II to the forefront of the United States, and many families from around Texas moved to Arlington to find jobs. Before World War II, the city's population had grown to over 4,000. The war kick-started a manufacturing revolution in Texas. Arlington was between the biggest aerospace engineering hubs in Texas at the time, Dallas and Fort Worth.
