The squeal of tires echoes from the ceiling as go-karts tear around the indoor track at Jam Raceway. Suspended inches off the ground, racers drive electric European karts that catch speeds up to 45 miles per hour. Each 14-lap race around the quarter-mile track takes about 10 minutes. Spectators can keep an eye on the action on the projection screen, which displays lap times and current standings. Drivers can check their statistics on the score sheet they receive after each race. The raceway's staff changes the track layout on a regular basis to keep racers on their toes.
