My last moment of stupidity (12-8-09) resulted in a broken ankle.
I refused to turn around and take another route when I encountered glare ice, all the way across the street I used to get to work. Not even coasting across it worked. Putting down the foot to catch the slide-out resulted in a sharp and painful CRACK! on the inner anklebone. It was a tough one, because it didn't show up on x-rays for five weeks (saw the originals myself). But I DID get a reputation for being something of an 'iron man' for riding and working with a broken ankle all that time.
