Studies show that the human body produces adrenaline in response to high speeds, physical threats, and getting called on-stage on The Price is Right. Experience the next-best thrill with today's Groupon: for $19, you get one 15-minute kart-racing session, license, and head sock at PGP Motorsports Park in Kent (a $38 total value). PGP Motorsports Park is open rain or shine.

At PGP Motorsports, voted Best Guys Weekend Destination by CityVoters, drivers test their motorized mettle on a 0.82-mile outdoor track that spans as wide as 30 feet. Self-chauffeurs start by picking from a fleet of Birel N35 karts equipped with ergonomically designed cradle seats, hydraulic brakes, and powerful four-stroke Honda engines. Once they've mounted their horse-powered chariot, possessed autoists will get 15 minutes to exorcise their speed demons as they propel themselves through the track's banked corners, exhilarating straight-aways, and 15 turns at speeds up to 45 mph. Racers should arrive 30 minutes prior to the kart session to get a sense for the track and to select the appropriate helmet to protect a bouffant.

PGP Motorsports Park encourages dedicated speedsters to race on rainy days, as the wet weather gives them an opportunity to practice drift-style racing without having to break open a fire hydrant in a cul-de-sac. Though jostling is expected in packs of motorized wheel-debeests, PGP prohibits aggressive driving, unnecessary bumping, and flagrant koopa shells.
