I can confirm that people just don't bother to set up WEP or any sort of security. When I went wifi a year or so ago I immediately picked up the signal from the pub over the road. Believe it or not he had his whole pub network shared, so I could peruse his accounts, correspondence, downloads from EDonkey (very entertaining.......) etc. He'd just left the wireless router set on it's default name, which was a bit of a giveaway.
