Go Kart racing!
First off, the waiver you have to sign here is a bit scary. Says if there is any bodily harm or you die they are not responsible. Not sure if that holds up in court, but whatever, I'll sign it I guess. My car was broken, as were about half of the cars there. Luckily they were able to switch me over to one that worked. Not sure who designed these cars, but it is a bit unerving to look down and see a gas tank between your legs. I'll be the first to admit, I probably suck at this "sport." I got lapped a few times by several more "experienced" drivers who probably come here every day. The cars do go FAST and I didn't want to crash since if I do I can't sue them for damages.
Overall, it's fun to do a race, but for $25 I can think of better way to entertain myself. I had just come from laser tag which was half the price, twice as long, and a much smaller risk of death or injury.
