I think SK has jinxed me!
Today I was in 25mph paceline, crossed wheels, and have pretty new blue sling for my left arm (fractured Humerus)
My previous worst fall (which resulted in a Ambulance ride). Descend at 30 - hit a patch of gravel - slid out.

Had about 10 stitches (Knee got banged up pretty bad), Broke a finger, and destroyed a helmet.
