I keep mine pretty simple... the state of Florida has vanity plates, and I've had a Univ of Florida tag since inception, and have an Alumnus tag holder...I drive an SUV so have a large rear flat window...American flag decal since prior to 9/11...LaRue Tactical sticker.."God bless our troops, especially our snipers" and Trijicon sticker since they support a sport I participate in, and agree with the content... I get a lot of "thumbs up" for the LaRue sticker
