Aviator,Really, is it that bad down there?
New Orleans is a very interesting and fun place, but you do need to be aware.
Years ago we did a tour of a graveyard in the Garden District. One of the first things the "tour guide" pointed out was that we all look like tourists (turns out we think he was a free-lance guy.....but good) . He said even if you think you dressed down to not look like a tourist, it doesn't work, you look like a tourist.
He then proceeded to point around and indicate what streets bordered the areas that would be OK. Even though it was daytime in the tourist area Garden District he added that literally crossing a street can make a difference.
During Mardi Gras we wandered around bar hopping on Bourbon Street. Lots of fun. Great variety of music and entertainment. At the one end we ran into a stationed police officer who told us there was nothing for us further on and to return to the bar area. It did look like the neighborhood beyond was a different environment.
Anyway, I love New Orleans, but yes, it can be that bad. The environment can change very quickly. Stick with the tourist areas unless you're with a local. Hope this does some good. AP/vic
