Update

I didn't have to go to Autozone after all because the light went off. With some engine errors, if the error goes away and stays gone after you've run the engine three times, the light will turn off. (This is true for VWs and Toyotas - dunno about other cars.) So I'm sure it was a loose gas cap. Since on a Toyota you can only tighten the cap so far (it clicks once and that's it), if I get the error again I'll have to get a new cap.

I went to vote and the polling place was hoppin'. At 10 in the morning. I don't know if this had something to do with people wanting to keep/get rid of our mayor, or if there's something more interesting going on that I don't know about. (I DO read the paper, believe it or not.)

I almost got a haircut while I was out and about, but then chickened out. I have to get back to work anyway.
