There are a bunch of scam artists dressed as monks who wander around tourist areas of New Orleans and it's the classic "Forcibly give or put something on you and then cry you owe them money" scam. I found being immediately super aggressive and rude got them to go away immediately. Honestly, it's just a giant shithole to be in. The battlefield boat tour is great. The world war 2 museum is amazing. Otherwise it's just piss, weed, junkies and drunks. It's a shame such an amazing museum with such amazing artifacts is in such a place. They have actual melted stuff from the a-bomb drops
