Don't ride your bike in the freezing fog.

You know how when the temperature is below freezing, fog can form ice on streets? Yeah, I wiped out going down Phinney Ridge on my bike this morning. TL;DR: I'm fine, but my bike isn't.

I spun around a little as I slid down the hill. That must have looked kind of cool if you weren't experiencing it.

At least this time there were no other vehicles involved. The driver of the car behind me stopped and checked in, which was nice, and said that it was a narrower escape for me than it seemed. Uh, yikes?

I landed on my right hip, shoulder, and elbow yet again, but this time I'm completely ambulatory if bruised and scraped. Yes, I have taken ibuprofen.

Here's the property damage:

1. I tore a hole in my serious mittens. That's not too bad; the grippy stuff on the palms was already wearing off due to — wait for it — riding my bike in them.
2. I tore a hole in my hi-viz jacket. It, too, was looking pretty grungy and therefore less hi-viz. Not so bad.
3. The handles of both my brakes are pointing in weird directions. I stopped halfway home and walked the rest of the way.
4. I couldn't even find the LED from my headlamp. Mind you, I wasn't too inclined to look hard for it because cars were trying to drive on the icy street I'd just wiped out on.

So, shopping at REI is in my near future.

As for the necessary bike repair, that too comes at a good time. My rear derailleur has become unreliable, which probably means I've worn the cassette down. I've ridden it about 3000 miles.

You know, the streets didn't look questionable for the first mile or so of the ride. It only takes one icy patch, though, and Seattle's many steep slopes don't help. Am I some kind of maniac or what?

Edited to add: I hope that wiping out on your bike isn't one of these things that come in threes.
