Some of the Mardi Gras celebrations in the big cities are pretty raunchy, but most of the celebrations in smaller towns are nice. For about four years, I attended the parade in a little town called Addis, Louisiana. I never saw anything raunchy at that parade. They just had the usual small town parade stuff. They had a bunch of fire engines to lead the parade. They they had the usual parade queen type cars. They had an array of floats that were typically decorated with Mardi Gras colors but sometimes had other themes. The end of the parade was always a mounted police guard.
