If you don't know what war driving is, your wireless router's most likely not secured, either. So get on over to OCModShop & edumacate yourself before you end up with all of your personal info on some forum somewhere.

"In the modern day of broadband and high-speed internet, people have migrated from modems to routers, many of which have wireless capability. 'War Driving' is the act of driving around in a car looking for 'open' wireless access points, usually with a booster antenna on the roof that is attached to a wireless LAN card in a laptop. But these days, this can also be done with a PDA, like an iPAQ."
