Euro Decals for Cars?

I just got a free Euro Decal (You know, the white oval stickers with the writing on the inside) of a city that I went to and loved (Atlanta). I was wondering if people found it stupid that people drive cars with these oval stickers. My sticker says 'ATL' and at the bottom in smallish letters it says 'Atlanta'.. I want to put it on my car, but I don't wanna look stupid.. What do you think?
