Sorry - forgot to take pictures.
The dude was driving a clunky old car, and had two huge stickers on its back. The first: "Linux... something something bla bla bla" (couldn't focus due the fact the second one practically rendered me blind while driving)... The second: "Ron Paul for president". Both black on white, both seemed like they were home printed.
The dude itself - derelict haircut, unshaved, chubby, mustached, about 50.
I suspected that Ron Paul has captured that demographic. You know - ex-hippy - awakening from a daze of marijuana - probably a virgin - conspiracy theorist - Linux nerd.
