A lot of people still don't feel safe going to New Orleans and I am one of them.
I feel perfectly safe going there and do so nearly every weekend. Also, what skysummit said. It is absolutely fine to go to CBD/Uptown/Garden District/French Quarter. The Audubon Zoo and surrounding area is also quite safe (and they need the visitors to help defray the costs of rebuilding).
Wow after Katrina and all are you guys serious about this? You sure there is no more debree, flooding, crazy people on the streets.
Well gosh, yes, since the whole place has been dry since November, the debris is cleared off of major roads/streets (it's just in piles next to it!

) in the areas mentioned above that experienced minor to medium flooding, and most of the harmfully crazy people are still not around. The vast majority of the endearingly crazy people that
are still around won't hurt you. There's quite a bit of people back that are working, going to school, and just living life in general there.
It's not a warzone across the entire city anymore.
Really and truly there are some parts that, while they still exhibit damage and the marks of rebuilding, are largely back to the new normal. Except for a few stop lights that don't work, some shuttered restaurants/businesses and the aforementioned signs of wind/flood damage and repair.
