Always a bummer. But better than hitting something! I had a contest with a deer years ago. (I won, he died) Got home with a ride from a passing stranger. It wasn't until the middle of the next morning that my "bruised collar bone" turned out to be broken. Back to the ER, and wore an "under the arms" brace 24 hours a day for the next six weeks. In July. But that IS really weird that you would have scratches on your other arm with your gear on!
