I don't find the need to argue about the smell of New Orleans to a bunch of people who obviously aren't biased against the city and have nothing else negative to say about it. The only place that stinks in NO is Bourbon street. Stay away and it doesn't stink. It's pretty simple.
Its not just Bourbon, NO is just a smelly city with trash and bad sewage everywhere. I prefer lafayette over NO any day for food and smell.
