Tulane professor and geographer Richard Campanella is a cool guy who does really cool stuff with maps and geography (if you're into that sort of thing). He had some strong words of support for the Oak Street Po-Boy Festival.
To translate this from academic-speak into plain English: "Events like the Po-Boy Fest are examples of how New Orleans still has all those cool local things that make us awesome. And we're more and more aware of how awesome and distinct we are. Meanwhile, everywhere else is increasingly the same."
Say what you want about the crowds at Po-Boy Fest, the man makes a good point.
