8 acres is plenty of space?
And that includes the parking lot.
Years ago, there were rumors of a WalMart Supercenter replacing Camden. The park isn't big enough for a Supercenter parking lot alone.
Plus, the park floods. and is adjacent to a sewage plant. And in a depressed and declining area.
When the Roberts bought Camden Park, they almost lost out to the Henningers. You may heard of them. What a better future Camden would have had. The who? They owned Kennywood.
Camden was on leased land at the time. So, the Roberts it was (they also owned Fun Spot in Angola, Indiana).
