I'm 54, and realized after riding around some local trails, with a friend of 31, that he was riding thru sections which I would have in the past, but now find myself walking. One particular section as a steep incline, with a banked dirt edge, rocky bottom, which led into a rocky, dried-up stream bed, then a bank up the other side. He rode down, and across. I walked down (just couldn't imagine the consequences of falling on those rocks if slipped off the dirt embankment). I did ride across the stream bed and up the other side. Kind of bothers me that I'm skipping the more technically challenging sections these days, but I guess better out on the trail, riding most, than none at all. Anyone else finding themselves more cautious these days?
