The first weekend in October, tentatively scheduled for our Lower Manhattan walking tour, is Open House New York. I would like to hit a bunch of places and hopefully you will too, so I want to keep that weekend free. I've decided the easiest rescheduling is to move it to tomorrow 9/18. We're supposed to have good weather like today and there should be enough time to finish before it gets dark. We're going to cover a lot more ground than our mini-tour the first day of class so please wear decent shoes.
