I am WAY late to this conversation, but my chapter uses a gator for our mascot. Our advisor that helped start our chapter in 1991 was from Florida and was a huge gators fan, so we have a BUNCH of songs and chants and stuff with the gator in it. And there are stuffed alligators all around our house, and passed during big/lil week and stuff. i love having a fierce animal! haha better then a butterfly in my opinion. haha just kidding!
