Younger? I'm not done yet.
I think most of it started in HS when we (and it was a mixed group, five guys and 3 girls, none of whom were ever romantic with anyone else in that group) discovered we could ski off the backside of resorts in Tahoe into areas where if we messed up, pretty much we'd be dead. But that was only winter, in summer we'd do technical climbing with the least amount of equipment we could get by with. Obviously safety equipment wasn't needed. Hell, it was going to take a silver bullet to kill us.
Every Xmas we'd take off the day after Xmas and go to Death Valley for NYE, where we'd spend a day and a half hiking/packing stuff (firewood, beer, not much else) up into some box canyon so we could do our annual Carlos Castaneda Unusual Occurrences in the Desert party, with the appropriate party favors. God I miss those parties, they were awesome. But again, a bunch of HS kids, out in the wilderness tripping balls all night long around a huge bonfire was perhaps not the best idea we ever had, but not the worst either.
3 of us road motorcycles from San Francisco to the Panama Canal, through Nicaragua during the revolution, that was most likely a bad idea.
Went on the road with a bunch of bands, some famous, some not - all of those antics, hi-jinx and shenanigans are pretty much unprintable (until I finish the book at least, but I'm changing lots, and lots, and lots of names). Let's just say your wildest imagination does not even come close. So sure, I can get you backstage honey, ask me how. Bring your friend with you.
