N.Y., N.Y., It's A Wireless Town
After spending a few months wardriving around New York City, a VP of a wireless network provider realized that most of Manhattan already has WiFi accessible to them. About 60% of the networks he found were wide open, and he’s hoping that with some better security in place, the others can open up their networks to the public (perhaps for a price), and suddenly NYC will have an ad hoc wireless network in place.
