Nothing wrong with the sign to me. I get the point he's trying to say.
In fact that sign could probably go on a national tour and stop at each town on the map.
Change "the Big Easy" to "insert your town name here" and he's prob right on.
"THE BIG EASY IS THE MODERN DAY SODOM AND GOMORRAH."
THANK YOU THANK YOU THANK YOU!!!! You are so right. That is the EXACT point he was trying to make. AMEN...
