Sometimes it's fun to post and read silly, irrelevant stories. My river injuries:
Twice fell so hard on some rocks that my entire butt turned a dark purple and I could hardly walk. I was stone sober both time. On a Grand trip some finger tips were shredded when I was under the boat. They were stitched up on a beach and I didn't row again.
I never played team sports but have had plenty of sprains, abrasions, and bruises biking, skiing, hiking, etc. loving the outdoors.
When the river calls, the wise one listen.
