The National Bison Range is about an hour north of Missoula, Montana. It protects some 400 bison, several herds of mule deer, elk, big horn sheep, as well as black bear, and several species of bird. On our visit we saw only herds of bison in the distance, as many roads were closed for the Winter Season, a pretty late event in Montana. And this is as close as we could get with a telescoping lens. Still, Sheldon got closer. Perhaps too close.
