Don't forget this part of the Wikipedia article, which is in reference to a ride that Tom discussed on that 2007 episode referenced above.
"In the mid-1980s GAR built an enclosed water slide, not unusual for that time, and indeed the park already had several. But for this one they decided to build, at the end, a complete vertical loop of the kind more commonly associated with roller coasters.[15] Employees have reported they were offered hundred-dollar bills to test it. "It didn't buy enough booze to drown out the memory", said Fergus.[11]"
I loved Action Park and I miss it a lot. The adrenaline rush was incredible. Now I have to punch myself in the face with a hot iron to match that quality and quantity of excitement.
