The best description I've heard of Shreveport-Bossier, Louisiana is that it's where boiled crawfish meet smoky BBQ. And if that sounds delicious to you, well, you're right.
Shreveport-Bossier is a unique blend of Louisiana and East Texas, and needed to differentiate itself from a more well-known Louisiana city. This logo addresses that issue as well as calling attention to the geographic location of the sister cities.
