Need a plan for a rainy summer day? Check out RPM Raceway in Stamford, CT, the new all-electric indoor go-kart track. In addition to casual racing on their two quarter-mile racing tracks, they have racing leagues (including a summer one for kids), a 14-lane bowling alley and virtual reality experiences. Don’t expect any lemon cars either—their cars are Italian-made go-karts that can reach speeds up to 45 miles per hour.
