This one time, back in the early days, I got blazed out with some real veterans in the woods. They left rather quickly, so I was left all alone in the middle of the woods.
Anyhoo, I felt powerful. Not strong, but powerful like a god. I went around demanding trees to sacrifice other trees to my glory.
But the highlight of the day was when I found these two skinny trees that grew parallel to each other, one at about sixty degrees, the other at about eighty. So I held on to to steeper one and and walked up the other. When I was as high as I could go, I just starting putting my weight down, and it would push me back up like a trampoline. This is all happening about twenty feet off the ground. I just sat there, doing that for about an hour, laughing my ass off, doing it over and over. But eventually it started to droop, and I rode that bitch out until it was flat on the ground.
So damn fun. I've tried finding other setups like that, but no luck. I don't know if that counts as a "geek out", though, because that'd be fun as hell in sober life as well.
