jlag, I bet if you were kind enough to approach either one of these groups and ask if you could lead the route they were on, or even to share their top-rope, they would not only oblige, but would probably learn a lesson from you since you are such a superior climber. Of course, a bad attitude and anti-social behaviour will always lead to the same results. I've had bad experiences with the Mounties in the past, but with that point of view, I can see they many things have changed.
