I mentioned bumper stickers on my site today, but you beat me to the rant I was planning about them. I'm amazed by how much the bumper sticker population in my neighborhood goes up on Sumdays - "Jesus is my co-pilot" and all that. I read someplace once that Americans are the only self-important culture to list our alma maters on our vehicles, be it Harvard Alumnus or My Child is an Honor Student at Podunk Elementary.
I'm amused by the places (such as Delta Cafe) who serve the 40's of PBR in buckets of ice a la champagne. Unfortunately, I've developed a bad case of beer snobbery since I moved to the NW and can't drink any of the newly chic "working man beers" like Olympia or PBR unless I'm already a few pints in. My wallet suffers for it.
