If you get over to the Samana Bay area, ask about the Capt Tracy. She is a treasure hunting boat that is working a shipwreck (the Scipion) in the bay. They are great guys to talk to and will even share some of their finds with you (to look at, not keep. LOL)
The company is Deep Blue Marine. Symbol DPBE. No, I'm not saying to buy the stock. NO advice given in this post. Just give you that so you can look up the comapny some.
The captain of the boat is named Billy. He is a great guy. The owner of the company is in Utah most of the time, but if he is there, his name is Wilf. See if he is around.
It may be a unique opportunity for you to see some treasure hunting on a first person basis. Just a thought. :-)
