This was a lot more fun and safe than I thought it was going to be. It's not the nostalgic go-kart bumping kind of race (which i'm totally okay with) its a best lap race. We went with a group of 24 and we had two heats of 12 with 3 races for $90pp including membership fee.
They supply free lockers and make you use their red face masks. At first, I thought this was unsanitary and kinda gross. You can't bring your own because they can't guarantee your face mask is clean. Their face masks are discarded every race into a bin and washed and each race you pick up a new one - so it wasn't so bad. The helmets come full faced with sizes from S M L XL XXL. The service was great on a Friday night, it wasn't too busy. A little slow to register but we were all new and if you forgot to register online they have computers on the side to do so. The only thing is they close pretty early on a friday night, 9pm. There is a height restriction, must be at least 5' or something and I think you need a drivers license to operate the karts.
The races are fun as long as you are with a group that go fast and don't crash/bump. Whenever anyone bumps or crashes all the karts slow down. I never got a black flag but our group got it 3 times - I think the staff were nice about it though, so it was all in good fun.
At first I was scared only because of the crazy testosterone in our group and their fearless urge to go super fast. But I actually did pretty good, thought it was safe and fun with a large group!
