No solidarity with rock climbers either. A favorite place to unleash loud and bothersome exhaust noise is in the Yosemite Valley. The sound echoes off the granite walls for the listening pleasure of those trying to enjoy nature's beauty.
This also annoys the climbers scaling the big walls.
One time a bunch of bikers cruised up to some climbers hanging along the side of the road in Tuolumne Meadows.
One of the bikers looked at rack of gear that rock climber extraordinaire Jim Bridwell was wearing an asked, "what are those carabiners made out of boy?"
Bridwell gave them the stern look and replied "ground up Harley parts."
They got on their bikes and left, smart enough to know they would get their ass whooped by a bunch of climbers.
