Just another reason for me to stay away from the boulders.... But honestly folks, they're pebbles in a forest. When a little boy pulls off a little flake, does it really alter your life so much? You don't even know if someone took a crowbar to it, most likely some fat guy was pulling a bit too hard. Think of it as enhanced erosion. Trash is another story.
Though I have noticed that an additional 50 lbs will make a slope sluff on me where my partners were fine. Guess I need fatter skis.
