Screw that.
Some people were talking about a new thing that was added up in Hocking Hills (state park in Ohio). It's called a "canopy tour." They put up a bunch of zip-lines going from tree to tree.
"Be the first to experience the more than 3200 feet of zip line cables and fly over rock bridges, fern covered gulleys and traverse the bluffs of the Hocking River. The two-and-a-half hour canopy tour experience will include a progression of 10 zip lines, 3 sky bridges, and a rappel."
You can count me out of that to. Me and heights aren't the best of friends.
