Well, I can only speak as I find. We spent a fortnight in New Orleans four years ago and loved it. We went out every night to the French Quarter and other parts of the city and usually walked back to our accommodation in an inner city area. We found a great atmosphere in the bars, clubs and restaurants with fantastic music and really nice (if somewhat boisterous) people. I was not propositioned by any prostitutes (even when Mrs H was elsewhere), we saw no violence, throwing up, very little bad language and no public nudity (worse luck!
).
What a refreshing contrast to Manchester city centre!
