Hemi-Challenger - talk to the car caller before going up into the lanes. He'll probably direct you to a certain lane, so that he knows you want a different tree. He'll call it up into the tower before sending you out.
Max-Maniac - all open pits this weekend, from what I understand
69dart - no, but there is a tire shop on Route 22 about 1/2 mile before you get to PRP. Many racers have used it.
dartman366 - if there is a line forming up before a stated opening time, PRP typically will open the gates earlier to keep it from reaching out to 22
Nice meeting you this weekend, Doug! Thank you and your granddaughter for the cookies!
