I don't know if anyone has posted this yet but since it is winter, here's an on-line video you can watch or download. Three Men, Three Rivers are the stories of George Grant-Big Hole, Bud Lilly-Madison, and Dan Bailey-Yellowstone. It is by the Montana Fish, wildlife and Parks. When you have a spare 30 minutes, give it a try.
