This place is a pretty cool track. I have been here for a nascar race and to drive a nascar race car as well.
As a spectator, sit in the covered seats, wear sun screen, and ear plugs you may need them. There are not many bad seats in the house, and it really is a blast to get a pit pass and go down and check out the cars/crews and general on goings in the middle of the track. If you haven't done so, do it at least once. Also note there are a ton of things to do there before the races usually. Be sure to check out whats going on.
As a driver. HOLY COW. I've always wanted to do this and this was my first chance. I want to race at PIR again, the dogleg is a little off putting if you have never driven a race car before but peddle to the meddle and go thru it the car takes to this track really nicely.
I am really glad we have PIR up here. Firebird closed, and I used to frequent Tucson Raceway Park when I was younger but Tucson is a long haul.
