Good to see you back, TimBob!
I love NOLA.....probably my favorite city on the planet. The city does have its "shady elements", but for me, that just adds to it's mistique.

I loved spending time there (while I was stationed in Mississippi), but I don't know how living there would be.
There's always something to do there, and the food is second to none (IMO). I did Mardi Gras once, and that was enough to last me 3 lifetimes. My advice is to go out and enjoy the city, but look out for yourself and your buddies.
I hope your Navy career goes well for you, and you enjoy your first assignment.
