A stream of yellow and black buzzes by. It's not a swarm of bumblebees, but friends and family racing each other in yellow and black go-karts around Checkered Flag Indoor Karting's 23,000-square-foot speedway. Strapping on helmets and sliding in behind the wheel of 15HP electric karts, up to 10 drivers jockey for position while whipping around eight snaky turns and sling-shooting past opponents on the wide lanes along the 100-foot front stretch. The facility's electronic timing system lets speedsters check out their best lap times from each 20-lap race. Racers must be at least 54" tall or born with tires instead of feet to traverse that track, but during birthday parties kids aged 4–9 and at least 36" tall zip across the 100-foot Mini Cup track. With a snack bar slicing pizza and pouring soda and an arcade, the facility can play host to parties for older kids and adults, as well as corporate team-building events. And for kids and adults seeking serious competition, Checkered Flag organizes leagues lead by indoor karting champion, Tom Prioli.
