The French Quarter
This was my third visit to New Orleans in just over two years. This visit, I finally hit my saturation point on the French Quarter. It's lovely and historic aside from raucous party atmosphere on Bourbon Street. But after three visits, I've seen really seen it. It's also not that large. It's one of those places that seems larger than it is because it's easy to lose your way.
However, whenever my fourth visit is, I'm going to rent a car and explore more of the city. I've taken the street cars out to the Garden District and City Park but there's much of the city of I haven't yet seen.
