It was so much fun to be at Custer State Park in the spring. Along with the Bison calves and the Bighorn lambs, the Prairie Dog pups were on display. We saw one family with at least four pups playing a rough and tumble game, even with their mom. The young, no matter what species, always have that irresistible appeal. This duo was rolling around in a scuffle atop their burrow, then they stopped, briefly looked in the direction of my lens, and then continued their playful battle.
