Truck driver's heaven. Flying J maintains 130 Travel Plazas across the United States, offering all sorts of amenities to them what hauls cargo in 12-hour stretches across big plains full of nothin'. Preventive maintenance, tire services, wash bays, restaurants, fuel, audio book rentals (just return them at any Flying J when you're done), and a store selling everything from electronics to three-dollar t-shirts to clean socks to tacky wood carvings of wolves and eagles.

I recently drove from one end of the continental U.S. to the other in a Budget rental truck. The periodic appearance of a Flying J was the only thing that kept me sane during the West Texas leg from Fort Worth to El Paso.
