San Francisco's Got Free Wi-Fi

Carpoolio writes "If you're living in San Francisco, chances are you can connect, for free, to the BARWN -- the Bay Area Research Wireless Network. BARWN broadcasts an 802.11 signal from the top of a big hill near San Francisco, and anyone with a clear sight line to the signal can connect. Another set of wireless nodes are being placed around town by SFLan, making Wi-Fi available to tens of thousands of people."
