To be completely honest, the first time I ever visited Boss PRO-Karting I thought I was going to die. I mean sure, I was driving around the track like a granny, but it was definitely spiking my adrenaline. I've been back a few times since and I've had a ton of fun while placing last each race.
When you first visit, there are a few steps you have to go through, but after you're in the system it's pretty straightforward. The place is great for events, group outings or small groups.
Boss PRO-Karting isn't the typical go-kart experience, but that's why it's so fun! (And it's definitely better than playing Mario Kart on the couch. Sorry Yoshi.)
