Swam in the Great Salt Lake in 1972 and remember it well. Someone had a few WWII amphibian troop carriers out there that you could get a ride in. I had to go there when driving thru on a long road trip and I went looking for this spot where I swam, it was all gone! All the buildings and wharf and docks it was all gone. The Saltair dance hall was still there up the road aways on the shore of the lake.
It sure must have been one heck of a place 50 years ago. They had some photos of the place packed with dancers and a live orchestra. It was a neat building, hopefully it survives.
