Racoons are VERY tough tenacious creatures. When I was about 13 or so, we went hunting racoons. We shot one out of a tree, it fell about 40-50 feet, landed on an old steel I-beam from a stripped down pickup truck, then proceeded to chase us.
"I'd feel better if we had some crampons. Oh, what the hell, let's go for it..." — Common climbing last words.
