I can see why someone would want to dive it but it doesn't interest me. It seems cost prohibitive and the boat ride out and a two or three day stay sounds down right unpleasant.
If I did want to dive it, my approach would be simple. I have the training and cards...yada, yada, yada but no notheast wreck diving experience. If I wanted to dive the Doria, I would spend some time diving other notheast wreck on a regular basis in preperation.
With the Great Lakes and all those great wrecks so much closer and more easily reached, the bang for the buck just doesn't seem to be there. To be honest, a nice quiet cave where I can do things on my own schedule without the hassles of a charter and usually less effected by weather suits me better. LOL, I can't hardly plan a trip on the Great Lakes without getting blown out or almost blown away.
