Black ice in a corner -- by the time it registered, I was already slamming into the ground: "Hey, that looks like..." *sudden pain, humiliation, anger...*

Most ignorant crash happened when I wasn't used to riding fixed, riding a conversion with a low bb/long crank combo and wide pedals, took a corner a bit too sharp and fast, pedal struck, lifted the rear tire off the ground, mconlonx get's introduced to 00-grade sandpaper, aka the road.
