Custer State Park

We drove through Custer State Park and saw some buffalo. But things didn't get interesting until we saw some by the side of the road. The people in the picture below are getting the scare of a life time as they drive by on their motorbike a buffalo is charging right at them.

But he wasn't serious and was bluffing as he pulled up and just grazed on the side of the road. Below he is calmly grazing. I think the noise of their bike irritated him.
