This is great info!! I go down to Avon almost every year with the fam, and every year I consider going diving there. I've talked to folks in both the Kitty Hawk and Hatteras dive shops, and between what they've told me and what I've read here, I know this kind of diving is not for me. Sadly its just too cold and rough for little me
BTW, I hear you can do a shore dive to a wreck off the beach in Kitty Hawk, although I have no idea how you can get into the water with all of those crazy waves and rips!
