Me and a friend of mine went WarDriving last night. I had my iBook and he had his Compaq laptop. We were running so many programs to sniff out wifi signals. I used iStumbler and MacStumbler. My friend used NetStumbler. My iBook seemed best because with NetStumbler on his laptop would disable the wireless card for connecting to networks and I was still able to sniff out and quickly connect.

We didn't do anything bad really. Just came across un-protected networks and changed the SSID in their routers to "You have been hacked" It was funny stuff.
