Mileage.

It took me about an hour and a half to walk about four miles today. I had a couple of hours to get from 72nd street down to 4th street, so I figured I might as well go on foot to use the time. I didn't get a lot of thinking done, which I put down to having to keep dodging and weaving through crowds - that kind of thing's easier when there's nobody in my way, on foot or any other method of transportation. Which is on me for sticking to a busy street at a busy time of day than walking a few blocks over and trying on that.

There's also my head's not here or there, and I need to find some space to drift.
