It’s been a while since my last Mardi Gras. But I do remember a serious crush of bodies, and the fact that it was a real pick-pocket heaven. If I was headed back, I’d go minimalist and just take the D7000 and the 18-200mm lens. That should cover you from the parade to the Bourbon St night scene. Maybe take the 11-17mm if you think you’ll do some indoor shots, but it’s awful hard to get indoors around the Quarter on that particular day!
