the president to let him drill a little deeper, he struck a large oil deposit, transforming Ranger into a boom town of 30,000. Oil was also discovered in the towns of Desdemona, Breckenridge, and Burkburnett. Fort Worth was strategically located between these towns, which stimulated its economy. Even before the oil boom, the city had three oil refineries. By the summer of 1920, five more had been built, with four more under construction. The First World War In 1917, the Canadian government established three airfields, named Taliaferro 1, 2, and 3. When the United States entered World War I, the fields were taken over by the U.S. military, with two of them being renamed Carruthers Field and Barron Field. Camp Bowie was built in 1917 on at a cost of US$3,000,000. Over 5,000 people worked on it, constructing over 1,500 buildings. Named for Jim Bowie, it is home to the 36th Infantry Division. After the war, it became a demobilization center, preparing soldiers for entry into civilian life before it closed on August 15, 1919. Inter-war Period In 1916, construction on Lake Worth (Texas) was completed at a cost of US$1,000,000. It initially had a capacity of 21,800 acre-feet, but this was later increased to 33,600 acre-feet. A group of entrepreneurs noticed that people often went to the beach for entertainment. They built a boardwalk, bathhouse, rides, and a ballroom, which came to be known as Casino Park. In 1918, George E. Kessler oversaw construction of a new, nine-mile long street that went through the Arlington Heights neighborhood. Originally named Arlington Heights Boulevard, it was renamed Camp Bowie Boulevard in 1919, in honor of the soldiers trained in Fort Worth who fought in World War I. The camp's commanding officer supervised the planting of over 700 trees, the first of many beautification projects in Fort Worth. In 1919, Norton Hinckley and David Tandy founded the Hinckley-Tandy Leather Company, which made leather shoe parts to sell to shoe stores. It was turned into a leather craft company by Charles D. Tandy when shoe rationing during World War II nearly bankrupted the business. The company grew, and in 1963 they bought RadioShack, an electronics store based in Boston. They were a competitor for larger electronics companies such as Commodore International, Apple Inc., and Microsoft. In 2000, Tandy Corporation officially became the RadioShack Corporation. During the summer of 1936, the Casa Mañana was
