WE just got back from a 3 week bike trip to Sturgis. We noticed that since there were so many bikes on the road that most never took the time to wave because they would have had their left hands always in the air waving. After spending that much time not waving we actually found that we enjoyed it. I don't know where the waving thing actually started but it was nice just riding down the road and enjoying the sights and sounds without all the waving. We actually found ourselves not doing much waving at all even on the way home.
