I'm taking my first trip to New Orleans AFTER Mardi Gras. I'm experienced at traveling alone and am very safety conscious, but I'm still a bit concerned from various stories I hear about NO. Any advice for a solo traveler? For example, I've heard not to go into a cemetery by myself and take a tour instead. Any advice is appreciated. I was planning to stay in the French Quarter and use streetcars to get around the city. Thanks in advance.
