Wi-Fi nodes there are. I took my Ax out with me today. I launched my wireless sniffer and just ran my normal route to work. About 85% of the nodes had the default name for the router and about 65% of the nodes didn't have any security on them whatsoever. It's a war-drivers dream! People! use SOME sort of security on your Wi-Fi.. WEP or WPA , Mac Filtering. Something is better than nothing at all even if WEP is weak.
