It was in the 60's today in Atlanta, so I took out one of the MTN bikes to get some trail riding in. About 3/4s mile in, on a downhill,I hit a major mudpit. Literly fliped over my bars, and was thrown several feet. The side of my helmet smashed on a large root. I hit so hard I was thinking well life was fun,"funny how fast your brain works in panic" I got up stunned, and covered in mud. I think I did bruise or crack 2 of my ribs. It hurts like all ****, to sit stand up cough or move in any way. But I am still alive. Moral of the story. For any of you who go out with out helmets "PLEASE, put those things on your noggin" I know for 100% sure, if I did not have mine on today,there would of been brain matter spatted on the ground and trees. I admit, I don't always wear mine when on paved trails, "thats going to change" but I always wear on dirt. I thank God I am able to type this right now.
