The Challenger II is a 32- foot piston-powered, nitro- fueled race car owned by Danny Thompson, son the famed speed king Mickey Thompson. Danny gave a tour of his workshop for local car enthusiasts. He plans his second attempt to set the land speed record in August, when Challenger II will speed in excess of 400 miles per hour over a 5 mile course in all of 80 seconds!
