At water street see if they'll let you set up in the video booth, clamp as far out as you can (there still might actually be a stud there to screw onto) and run DIN. Be careful if you run on the rail for the crowd from the balcony as right in your mic path to the speakers there are people, and often loud ones.
IF you cannot get in the balcony, and often they won't let you. Go underneath the overhang, but right at the edge of the center, get a few people to block and run DIN, I emphasize block here. I've lost a few pieces of gear to wooks at water street.
The owner of the place, John, is really friendly to tapers, so you shouldn't have too many problems gettingor setting up.
Good luck.
