One of my newer hobbies is war-driving. If you are not familiar with what war-driving is, simply check out sites like Wardriving.com and Netstumbler. Basically, it's driving around and discovering wireless networks. I war-drive with one general purpose--to gauge the growth of WiFi (802.11b) use in the Northern Virginia area. I do not war-drive with the intent to steal Internet access, sniff network traffic, or break into computers. In fact, I usually don't man the laptop--I simply drive.
