False. I think you'll miss the Jazz and Blues festival (IIRC it's sometime earlier), but in good news, you'll probably be just in time for absolutely brutal humid, hot weather. Sounds like fun, anyway, though — lots of ways to beat the heat, by choosing carefully one's venues. Personally, I'd think a little bar or café with live music would be ideal, but who knows.
TNP thinks the Indians (sort of also related to NOLA, but those are different Indians) are hot this season, but hasn't been following enough to be too sure (yes, that's the baseball team I'm referring to).
