There are at least a dozen wireless networks visible from their house up on top of a hill. There is an open and unfiltered one close enough to use. There is one for the school across the street. There is free one for Socal Free Net unusably far in Carmel valley. Half of them are using the default SSIDs: “linksys”, “default”, “NETGEAR”. There does seem to be some correlation between openness and default settings.
