I was rolling down Left Hand Canyon near Boulder Co doing about 35mph when i hit a fist size rock. The front tire went flat in two revolutions. ( for some reason I watched the front wheel ) I crossed a traffic lane on a tight curve. Grabbing all the rear brake i could get and i went 30 feet towards the creek. I was lucky most places along the road you have a few feet before the creek here i had about 40 feet and used most of it getting stopped.
One of the things i learned from reading cereal boxes was that the hero always avoided danger. At the beginning of the story he would avoid the danger created by the writer in the previous installment. In that case I believe i avoided "great danger"

Still have the bike did 40 miles on it yesterday
