After checking both websites,I think Boschertown is my choice. It seems like that Pole Position is too worried about liability,plus they are little more expensive...JMO..
Boschertown is just an outdoor have fun kart in place where you might only have 3 or 4 karts on the track. Pole Position is in a whole different league. On any given evening you will find plenty of race car drivers all racing against each other.
They're more worried abt liability bcuz like jd said its in a whole other league. Boschrrtown is like branson/ozark kiddy karting. Go to pole position if you're the least bit serious abt it.
