Many of you know i wrote off my snowmobile last winter when i hit a tree doing about 35-40 miles per hour. Went and had a look at the tree that i hit last weekend. This is what i saw:

Bottom tree wound is from the snowmobile impact which twisted the steel frame and destroyed the right front suspension and ultimately made the machine a write off. Top wound is from my head - no helmet.
Close up of head impact site:

Somehow only a minor concussion - was on light duty for 5 days - should have killed me. Did split my scalp and gave me a tennis ball sized goose egg. Always been an adrenaline junkie but after 62 years of pushing the envelope hopefully i have finally learned something. That is my 12th or 13th concussion and hopefully my last.
