Bison!

I will admit, Bison is one animal that you see PLENTY of in both parks, and one not always worth stopping for, really. However, the last day I was there, after the huge snow storm the night before, was defiantly a bison day. They really stood out against the snow, and it was a great time to really stop and spend some time with one of the herds. The babies loved the snow, even though i pretty much froze!
