Thanks! The bison definitely seem more intelligent than cattle, though they also seem a bit more lethargic. Some of that is probably because it's so cold out but, even in the summer, they don't like to move fast unless they have to.

The park ranger was worried the one trying to cross would go through the ice and break a leg.

Funny that the cows fall for the paint job. They're not really known for being the smartest creatures... lol

The state park has a quite large bison enclosure wit cattle guards on both ends, so I usually get photos from my vehicle. In the summer, I occasionally walk the fence and get some photos that way, too. You wouldn't want to be on foot near them, though. I've seen them try to skewer people through the fence who were trying to take selfies with the bison in the background. They were far enough away from the fence. One heck of a photo bomb!
