wow
it looks like Rolling Green Park was right on the river! I would have loved to have seen that park. A housing development now? Ugh. The inevitable. I have so much respect for Knoebels and the longevity of that park.
Jason, what is the zipper you mentioned? I have a ride in mind that comes to our county fair most years, it is called the zipper, but it could be a completely different ride.
By the way, thanks, Vers, for googling that to share. I was just down in Selinsgrove today!
