But how does one go about forming a group to get their city to go wireless? Looking around, there are a few articles out there, but most deal with selling it to businesses. I haven't been able to find a definitive guide to "Getting your city to go wireless". So I send my plea out to the Slashdot community - just how does one go about getting your city to go wireless?"
