I did take a tumble last week. Going down a hill I go down 7 or 8 times a day, 3 or 4 times a week. One of countless places along the trail with loose dirt, rocks, leaves -- just ready to "get" you if you get a little careless.
My head hit the ground hard. Must have stuck my right arm out, cause I sprained that too. Thankfully, no permanent damage. It DID scrape my head up pretty good -- just in time to help with my Halloween look!
Well, I don't remember, but, since I sprained the right arm, logic tells me that I was carrying my hiking poles, unused, in my left hand. There's a lesson there...
