Letting the air out of my tires...

The ride was not to be. I was all set to bike to Bristol when valve head problems prevented me from putting air in the rear tire.

A couple weeks ago, I played the chivalrous one to a friend of mine from middle school after she got a flat prior to happy hour Tuesday night. I gave her my spare tube, and took her busted tube home to patch. Problem was, the Presta valve head got bent, and has a nasty habit of unscrewing itself from the valve housing. That, and it doesn't seem to want to accept any air into the tire. A flat later for me, and I'm without a reliable rear tube and a spare.

I have tubes in my spare wheelset, but I didn't have time to swap 'em out and ended up driving. Fun, fun. Didn't do any riding at all today, so tomorrow has to be better.
