Actually, folks like me usually opt for Rebel Flag bumperstickers or front tags. I have never seen anyone outside of the Dukes of Hazzard with a painted roof Rebel Flag.
I saw a TV show the other night about some French dude who had re-vitalized the French national soccer team. They had a shot of the championship game being played somewhere in Europe and to my amazement, right in front of the camera was a huge Rebel flag being waved. Go figure. I prefer the Bonnie Blue myself.
