On my commute home today I saw the first Oppo bumper sticker I've yet seen in the wild. I didn't get a picture due to post-rush-hour freeway driving*, but it was on a bright yellow(!) Nissan Frontier crew cab. Nice truck, fellow Seattlite Opponaut!
(* I may have been driving slightly more rapidly than usual in order to fulfill a promise to get home and cook dinner for numerous inlaws).
