Looked up Dillon, MT in my handy-dandy roadmap. It's way south of Butte, MT, nearer to Barretts Dam Recreation Area (closer to Montana's southern border), a place loaded with campsites.
Are there Indian Reservations near Dillon, Montana?
The muslims have been moving into the indian tribes near the Cana Border, converting the indians, taking indian wives and then getting papers that show they are indians.
I have read that they come and go across the border to Canada on the reservations.
