A lot of bumper stickers nowadays are very easy to remove and don't leave any damage.When I was first learning how to drive, my dad told ma not to put stickers on because it would lower the trade-in value, I think? Idk, I never did. I guess I could put magnets on, though. I'm supposed to have one fpr the school I teach at as marketing, but I don't know where I put it. I've thought about getting a cat one from Lelia's TNR, but haven't.
