We stopped and hiked to a fire tower, but the tower itself was locked. Then on our way home we came across this bison who was giving his friends a ride.
Do you see the birds on the bison's back?
We actually saw two large herds of bison today, one in Custer State Park, just as we were leaving to enter Wind Cave National Park, and the other right outside the entrance to the visitor center at Wind Cave National Park. On the way back we passed through the herd in Custer State Park. And I do mean passed through. Cars were backed up both directions waiting for the bison to cross the road.
