Carlisle is amazing. If you cant find it it doesnt exist. I Also go to the one in Englistown NJ. In the past few years though, it has become a junk sale. The last few have started to become more car parts and less ****. If your in the area its worth checking out, but otherwise, I wouldnt make a special trip.
I agree with everyone... the show is huge and has a little of everything. Even if you don't need anything... you will walk away with something before the day is over.
