Last year I visited my little dual sport in AZ. It had been left there from the previous season when I rode the CDR. On this trip I was struggling trying to complete Camp Creek Wash, which is a big natural drainage that goes about 12 miles and drops some 1500 feet to Rio Verde. I logged onto this forum for tips to help me out. Finally I spooned some fresh knobby's and freshly armed with my tips, I made that wash end to end without any drama.
One of the inmates then invited me to join him and another rider for a trail ride somewhere around Bumble Bee. So I showed up at the agreed spot and pulled off my helmet. After a long pause, the inmate ask's me "How old are you anyway...?"
The day went well, although something called Turkey Creek fairly kicked my ass... I was 64 at the time, but the other rider who joind us was my age too! Of course, he was a lot more skillful than me. But it was a really good day.
I've noticed there are a lot of riders of my generation still doing dual sport charity rides and such. For those that still compete, they even have special classes for us.
