Rusty,
The Yellowstone country is so marvelous, but add this for your next trip...
Head out the Tower Junction exit, the NE exit of Yellowstone Natl Park. That take you for about a 26 mile trip along the river, usually full of wildlife, and on up to Silvergate an then to Cooke City. As you go through Cooke City and out the other side, you will see a turn in to the Lulu Trail. Take that left turn and go about two miles and you will come to this pair of green gates, always open, and there are six wonderful, flat, gravel camp spots with views of the Beartooth Mountains all the way around. You can camp there and drive the Beartooth Highway to Red Lodge, MT an absolutely beautiful drive. Lots of trails right in the area you camp for your Bronco.
What's the old saying, "try it you'll like it"
