A few months back I was at the local Petsmart; getting out of my car I noticed a guy walking toward the store. I thought he looked familiar, so I looked back over my shoulder at him again... I didn't really recognize him but I thought he might have been somebody famous for some reason.
Anyway, when I got back to my car I saw that yellow mercedes, and when read the plate holder saying "Mr. Linux. King of Geeks." I figured out who it was, kind of neat.
At the time I don't think I realized he lived in Portland.
