I'm not big on bumper stickers, but sometimes you can add things without them being tacky...


Corny maybe, but not tacky.

Anyone who's seen my Halloween pics will understand though. And yes, they are on both sides, and the window was washed before I put the on (the dirt smudge came from hosing down the rest of the truck afterwards). Now I just have to remember to avoid those spots when scraping ice this Winter.
For anyone interested, I got these from Wreckless Decals (ebay). Very nice quality foil stickers, fully cut out.
