Everyones comments has helped me remind me of some of the attractions.
The images of the grass skiing that was next to the two terrain slides has flooded back, (totally forgotten that). They used to look like Bulldozer wheels with big, bright red tread.
Also, what has fasinated me is the massive, nastiest vertical half-pipe, (70's style) skateboard ramp that WAS where the mini golf was. That ramp was absolutely deadly, deep hidious vert on it. I wonder when the mini-golf was constructed if they just filled it in or did they fully remove it. (It was dug into the ground, fully concrete half-pipe. Nasty)
