Warparking
With a new law this year in California that forbids turned on computers in the passenger seat, the term Wardriving may be obsolete (unless you view it as a battle to not get caught).
On days when I am driving from meeting to meeting, scanning for Wifi is a must (thank you MacStumbler!). When I am in a pinch in downtown Palo Alto, you will find me parked aside the Apple Store. Funny thing is lately I noticed others similarly parked, getting work done on their laps.
I'm afraid unless there is more free Wifi available soon this may mean war.
