After reading everyone's flat tires I wanted to post this:
I did not have a flat tire today.
In fact I haven't had a flat tire in a long time. Don't remember when the last one was, I'm guessing 1.5 years.

The only excitement on my commute lately, since the new bike lanes went in, is that the major north-south street near us is undergoing badly needed repavement. It's all torn up right now. I use it for 1/2 block to get to the bike-laned east-west street. I could cross over it and take the next street, but I can never seem to remember to do that. This morning just after I signaled my left turn I remembered it, but there was a truck behind me, and I didn't want to confuse the truck by not turning left after I said I was going to turn left, so I turned left! Maybe I'll remember tonight.

It's so hard to make little adjustments to a daily route. Not long ago I decided that I was tired of dealing with the traffic in front of the post office, and 4 stop lights in a row (which are perhaps 1/4 or 1/3 of the stop lights in the entire town). If I jumped a block north I could avoid both the post office traffic and have stop signs instead of stop lights. It took a couple weeks of to remember to do it even once!
