Closest thing I have.
I did promotional work for a company that involved driving a themed car all around the, East Coast, Southeast area the summer of 2004. Me and a co-worker, long time friend.
Our travels took us near New Orleans so we decided to drive a bunch to set us up for a couple extra days in The Big Easy. We pull in with our cartoon car. People everywhere, partying, pretty much chaos. I go to check in, figure out the parking situation.
The lady at the front desk asks me if I am there for the festivities. I say no just work. She gets this funny look on her face. I ask her what is going on and she tells me it's "Southern Decadence Week". Not sure what this is, pre smartphone where you know everything about everything.
She tells me it's the gay man's Mardi Gras.
I look around the hotel and it is on. Dudes in biker outfits, sailor outfits, chaps the whole deal. Some pretty odd elevator rides that weekend
