Actually, (and someone who knows more about 802.11x then I do come in and fill in the blanks) many companies do not go to the trouble to secure their 802.11x networks, so you can just set your wireless NIC to "discover" mode and drive around town until one pops up. I saw an article in pc magazine some time back where they did that, they found you could access the internet, and sometimes, the internal networks themselves, all through unsecured 802.11x access points.
