Google maps pedometer. Useful for planning running or walking routes. Saturday, which was the nicest day in human history, I apparently went 5.6 miles, passing through three different municipalities as I did so. And one of them, I went all the way across, northern city limits to southern city limits. Yes, I was so impressed with myself that I had to post it on my blog. Pathetic, I know.
Still, that makes six different cities that I've run to or through from where I live, counting the one I start in. Chicago suburbs are so small.
