I love podcast walking tours (having started a company that used to make them, and then creating an award winning project for Philly) so whenever I come across a resource I note it. I also love Open House NY and too often am out of town and even if I'm here can't really visit more than four places at the max. So it is a great treat to find that they've been making tours of some really interesting places that you can visit anytime or from the comfort of your computer.
