In my humble opinion, that Big Hole River country is some of the prettiest country there is on this earth - specifically because it isn't all "grown up" with people yet. If I had the money - that's where I'd live out my days. (The winter's are harsh though). But alas, I can't afford it up there. [Sigh].
I didn't know Hank Jr had a ranch there. I knew he used to have a place over on the Gallatin River - maybe he still does.
The Loading Room is my favorite place also. It's peaceful.
The Big Hole, the Beaverhead, & the Ruby rivers come together in a place called Twin Bridges, Mt, and form the Jefferson River. The Jefferson flows down to a place called Three Forks, MT and joins with the Madison & Gallatin rivers - to form the Missouri River. All of these are world-class trout rivers - and I've fished them all. Truely magnificent country.
