I was sidehilling across a slope on one ski and clipped a rock that sent me tumbling. My sled went for a ghost ride directly for a patch of quakes below. It hit a good sized one hard enough that the top part of the tree snapped off. I was sure there was major damage and maybe a totaled sled. Total damage - a slight bend in the front of the lower a-arm, the top part of the tree broke a couple of inches off the end of my windshield when it snapped off, and some scuffs and bark on my front bumper, side panel and shock reservoir. Thats it. Luckily I was wearing a tether so it slowed the sled down a little and had Teth-Air's brace on on the lower a-arm so it didn't bend in the weak spot. Either someone was watching out for me or I was just lucky. I think some of both.
