Chance of having a good time while drifting and/or spinning, 100%.
Regarding rain... We have until 9am to decide whether to cancel and get a refund from the Stadium, or to continue for the day. Unless we have enough rain for there to be standing water on the track, we normally go ahead and run. A little mist or sprinkles won't stop us from running - in fact, it can be an excellent learning experience to drive in a cool/damp environment.
