Cool news for people in Milwaukee... free wi-fi is going to be set up in two downtown parks within a month. [article here]
It's really a perfect civic intestment, since it costs next to nothing to set up, and everyone loves it. I think that makes Milwaukee only the second city in the us to do this, after Long Beach.
I wish someone would do this in London, but alas, the only wireless networks you can find are pay-per-use ones which cost a fortune.
