In the summer of 2003, Killeen Engineering & Surveying was proud to be a part of the reconstruction of the Sonic Drive-In in Gatesville, Texas. Sonic, America's Drive-In is the nation's largest chain of drive-in restaurants.
Sonic originally started as a hamburger and root beer stand in 1953 in Shawnee, OK, called Top Hat Drive-In. Top-Hat's slogan had been "Service With the Speed of Sound", but with the changing post-war world, the Atomic Era, the Jet Age and the Space Race, the Top-Hat Drive-In changed it's name to SONIC.
Sonic has more than 3,000 drive-ins coast to coast and in Mexico. More than a million customers eat at Sonic every day. Forbes magazine named Sonic as one of the "200 Best Small Companies in America"; Business Week magazine named Sonic to the "Hot Growth Companies" list; and Entrepreneur magazine voted Sonic to its "Franchise 500 list".
