I remember pictures in my 4th grade geography book showing people floating high in the Great Salt Lake. A couple of us drove to Antelope Island State Park in the middle of the Salt Lake and tried it out for ourselves. It was pretty cool. There were little flies on the beach, but they were not bothersome. We saw bison, a great sunset, and even dropped in on a public star party of astronomers. Probably the most impressive part was how quiet and peaceful it was.
Just standing in the open with a few birds singing in the distance was very nice.
