I have only been to Maple Grove once (2012). Dress Warm. Be prepared to lose at least 1 session to rain, maybe even a whole day. 2 lane road in and out, be prepared for traffic. I stayed in a hotel in downtown Reading (old and dumpy town) and it was at least 30 minutes each way with no traffic. The facility is nothing special, they had people hustling for tips at the porta potties, I have never seen that before or since. Not a very compact pit area, the pros are packed in nicely and it's easy to see most of them, but if you are going to the sportsman pits it is a long walk and will likely be in grass and mud. They have Yuengling on draft! The area surrounding the track is gorgeous, and the fall leaves should be in full change. Go early, stay late, bring a good jacket and you should be fine.
With all of that said, the only real reason to go to Maple Grove is because the track is FLAT OUT FAST. When I was there in 2012, Top Fuel was throwing out low 3.70s like they were nothing, Funny Car was in the 3.90s and Pro Stock in the high 6.40s ... all of them with BIG MPH (over 330 in top fuel!) It was A LOT of fun as a spectator to sit there and watch the performance show they put on. Cruz Pedregon ran like a 4.02 or .03 and in his top end interview said he was disappointed in that run, that they left a lot on the table LOL. I would absolutely go back even though Reading is dumpy and the track is no where near as nice as Vegas or Norwalk.
