Palm Beach Karts, Jupiter

At Palm Beach Kart Center, drivers zoom around paved curves and sprint to the finish line in go karts reminiscent of Formula 1 race cars. Before each heat, competitors pick a number, strap on a helmet, listen to the safety rundown, then wait for the green signal. And like that, they're cruising at top speeds, veering around opponents and jockeying for the lead position and unanimous agreement from friends that sponsorship deals are forthcoming.
