I alway think of the time I got fried doing the Border Route Trip in the BW... Was wearing shorts and thirty years ago our shorts were short and got pretty sunburned. Got to a beautiful island campsite on "Big Sag", tore off my clothes and jumped in. I didn't know it was possible but when my toes touched the cold water I literally walked on water to get back on shore. I love to swim... but I go in with care now. I think the water on Big Sag is as cold as Lake Superior. I've only done the rock jumping once (and made it into the water) on the Lake One Chain... It was a blast!
