We were very fortunate on our trip to South Dakota, while driving in the Wind Cave National Park to come across this large herd of Bison.
It is something special to see these big animals up close, in their natural environment. We stayed with the herd some 30 minutes and actually drove on the road (slowly) alongside several members of the herd as they moved from this valley to the next.
I love the number of animals, spread out across the valley with its varied terrain. The blue sky contrasting the green grove or trees and the grass below.
