I have a pedometer built into my iPod Nano. Getting 10,000 steps a day isn't all that hard. I manage it almost every day. A couple of days ago, I was close to 26,000 steps. I was out in the evening and I didn't want to leave my bike outside, even locked up, in an unfamiliar neighbourhood in a strange city. It would have been safe, but I didn't know that at the time. Still, the walk was pleasant and I had a great evening.
