The National Hot Rod Association, the largest auto racing organization in the world, has come a long way since Wally Parks founded it in 1951. Though it has grown into a global sports-entertainment business, NHRA has not lost sight of Parks’ original goal: to provide competitors a place to race. But now those places are deluxe supertracks in major U.S. markets, and the racing runs the gamut from 10,000-horsepower Top Fuel dragsters to five-horsepower Jr. Dragsters. Drag racing’s journey through the decades has been sometimes swift, sometimes rocky, but always exciting and always worth the trip.
