Thanks for getting back with me, though I must admit that Heather answered most of my questions. I dove about three years ago with Down Under in Orange Beach. They were pretty efficient, but we will probably stay in Pensacola when we come down. Though I live in Alabama, Pensacola is actually a little closer than Orange Beach. One of the members of my party is only OW certified so according to the information on Capt. Dave's website he would have to dive with a divemaster. I think he is a couple of dives short of having 20, but by the time we dive the Oriskany he should be okay. Thanks for the help and hopefully we will get to meet this summer.
