I'm not, but wanted to wish you good luck! I did the Cape Henlopen Tri in Lewes, DE yesterday and the swim was cancelled because of rough surf. I hope it calms down for you this weekend.
I won't be at the event, but I've heard great things about it. You'll be fine, my first tri was nearby (Pocomoke) and the terrain in that area is perfect for a first race. Good luck!
