I used to have some land about 10 miles west of the old Fort Bonneville site about 10 miles west of Pinedale, WY. At the time, I think, it was on a private ranch. I don't know the status now since the Pinedale area has turned into poor man's Jackson Hole. The poor adjective is a relative term since you have to be a millionare to afford it rather than have 10 million needed to live in Jackson.
I dropped into the 1838 last year. I didn't get there soon enough to do any shooting but had a good time hitting the traders and seeing old friends. The biggest shock was seeing Big Ted clean shaven. He flipped me off when I told him to grow it back to save all the mirrors in camp. Some people just can't take any criticism.
