Not sure if anyone has asked or not , i think i looked at this whole thread, but do you have anything to post in the future of knoebels and williamsgrove in pennsylvania ? I do have these couple things , the pamphlet i believe is from the 80's, it still has the jetstar on the front.
Then i have the 2 post cards that where from the 80's, the one of the phoenix was when it was first built, you can still see part of the parking lot in front, i remember as a kid that was the main lot before they started using the field that they use now.
