Perhaps the scariest critter of all....proof that the snowboarder is the evolutionary step between Bison and skier......Proof you ask? Note the dragging knuckles, ala CroMagnon man....
When the critter is this big...you don't mind being ignored!
We were able to snow mobile on the roads of Yellowstone, and to get very close! I don't think snow mobiling is legal there any more. They had a low speed limit, but if you are new to it, and to see the park....it was time very well spent.
