Man, you said it. I don't know if they use the same thing these days but that friggin figure 8 brace wore a nickel-sized hole through the skin under my arm.
And having to go to school with elbows raised as if you're about to start flapping and take off. I hated that episode but in retrospect, I figure if that's the worst thing that has happened to me on a bike, I'm in like Flynn.

I did crash one time coming down Little Cottonwood Canyon in Utah when my front tubular decided to de-attach itself from my rim, but it was all just rash. Lots and lots of rash, but no broken bones. Thank Bog.
