That sounds familiar.
A few years ago I was on the South end of Old Ore. I came up out of a low spot and the road ran straight off into the distance... So I started getting on the gas. I had not gone far at all and was moving pretty good when my vision returned from the far distance at the end of the straight to what was right on front of me when I realized there was NO ROAD in front of me!!
There was a dry creek on the right that had eroded all the way across the road to a tree that was originally on the left side of the straight road. The new road curved to the left AROUND the tree and then back to the original road. There was on room to go straight and squeeze between the tree and the edge of the drop. So I slammed on the brakes, managed to swerve hard left, then hard right around the tree, and hard left again to get back on the straight section of the road. I would have made it too... But there was this one BIG bush with a BIG branch sticking out jusssst far enough to slap my left hand guard and plant me on the ground in an instant
A fewwww more inches and I would have been good. I got off pretty easy, just a minor tweak of the left ankle that never even swelled. It could have been a LOT worse...
I hope he heals quickly and completely.
