Mardi Gras is not just in NOLA.
My hometown has the second oldest Mardi Gras in the state. 2 parades on fat Tuesday. A little town of less than 5000 would swell to 60,000-110,000 people depending on the weather. Took a week just to clean the trash on the parade route. Citizens were left to clean all the rest on the side streets and their personal property.
All business have to close and lock up for the day or be robbed blind.
Lots of drunk, belligerent folks who will assault you on your own property.
If you let them....
