markbach,

Point well taken, but chances are you're looking at lots of APs provided courtesy of the country's oldest and biggest open wireless network. Or it could be the free, open wireless Internet access provided in that neighborhood by the King County Library System in that neck of the woods. Or one of the many coffee shops that provide free wireless net access.

Just because the network is accessible to you doesn't mean it's a security issue. Seattle's a pretty nice town, and there are lots of folks who don't mind sharing.
