My younger brother and I used to dive off of Destin. For those who do not know about the Mississippi River and its effect on the Gulf, Destin is the first port East of the mouth of the Mississippi River which is clear enough to see underwater. The effects of the Mississippi River dumping tons of silt into the delta are felt until Destin. I had an older cousin who lived in Fort Walton Beach who almost lived diving in the Gulf! ;-)
Now my nephews are diving off of Destin.
It is sad to see the S.S. United States becoming an atificial reef but it was simply rotting to nothing in Philadelphia so that I suppose that it is a good thing.
At least it will be a useful thing, whereas the others of that era are lost or were scrapped.............
