At the New Museum's Ideas City Festival a few weeks back, I got to meet radio producer Krissy Clark who teamed up with StoryCorps to usher in a new type of audio touring, using cell phones. The idea is to download their map of the SoHo/Village area and when you come to one of their designated story areas, call a particular toll-free number and hear a story about that area.
It's a novel idea worth taking note for all oral historians or aspiring tour guides out there. I haven't done it yet but I will as soon as I get myself into Manhattan. For anyone who's tried it--I'd love to hear about your experiences!
