Go-karts allow people to experience the thrill of driving without having to hear radio ads for pungent soaps or look at four empty seats that remind them of the time someone stole their family of mannequins. Keep thrills pure with today's Groupon: for $15, you get a one-year membership to Full Throttle Indoor Karting (a $30 value) and a head sock (a $2 value). Membership is $20 for youth younger than 16. The 12-month membership includes:

• Two races (one at any time and a second during your birthday month)
• Access to special events

Racers zip around the 14-corner track at speeds of up to 40 mph in Full Throttle Indoor Karting's 51,000-square-foot facility. Guests jump into the 9-horse-power steed, revving the 270cc Honda motor to glide their Sodi go-karts around the track's bends, avoiding barriers and flinging turtle shells at nearby opponents. All of the racing warehouse's roadsters are outfitted with adjustable seats, columns, and pedals to accommodate jockeys of all sizes, and the karting emporium also stocks youth karts. Full Throttle maintains a safe track with shock-minimizing barriers, highly trained track marshals, and full-face helmets and neck braces for all motorists who don't have a natural exoskeleton. Speedsters can tote along a loved one or family member who can catch the race from the large viewing area, or organize their own crab-walking races in the spacious lobby.
