Opinions are like apples, but my friends and I like Pole Position Raceway and their tracks in Temecula and Corona. They use the same electric karts and they are really fast.

It really is a better experience and they have air conditioning throughout their entire facilities and their karts seem to be better maintained. I believe they have 7 tracks and just started franchising so I'm assuming that there will be more
