I hope your bruised bum and ego both recover soon.
Two weeks ago I was riding bikes with the family along Anchorage's Coastal Trail. My youngest son (8 yrs) suddenly stopped in front of me. I hit the brakes, flew over the handle bars and landed on the pavement. Thank heaven my graceful dismount happened at a rare moment when the trail was clear of other bikers, walkers and photographers. (Lesson learned: no sightseeing while riding my bike.) A friend of mine with a very avid biking family said in regards to our first bike outing of the year: "Cool. First Blood! That usually happens to me."
I didn't feel like Rambo one bit.
