Full Throttle Indoor Karting, Florence

Racers zip around the tracks at Full Throttle Indoor Karting's massive indoor facility. Engines roar as tires grip the concrete sliding around turns. But there's one sensory experience missing: the smell of gas exhaust. That's because the karts are outfitted with custom catalytic converters that reduce gas output, helping ensure a cleaner racing area.

• The tracks: The 11-corner Rush track is large enough to form multiple racing lanes, while the quarter-mile Adrenaline track demands driver precision to reach top speeds.
• The karts: Both pro and junior karts are state-of-the-art SODI models powered by Honda engines. Junior karts top out at around 22 mph, while pro karts go up to 40 mph. Little ones ages 3-6 can take their first drives with micro mile karts that go around 6 mph.
• Leagues: Drivers can race for position, points, and trophies, testing their mettle against competition.
• Axe Throwing: After safety training, the competitive take to hurtling sharp axes at wooden targets to prove their might and aim.
