From the story: The city's new Wi-Fi network is unique in the nation in that it covers a large, 90-block area, provides two hours of free access daily and allows users to surf at speeds comparable to a DSL modem. For more time, higher speeds and better security, subscribers can pay $7.99 a day, $14.99 a month or $119.99 a year. The operator, US Wireless, makes money on subscriptions and ads.
The US Wireless site has a coverage map. (http://www.uswo.net/wifi.htm)
