No lack of animals in the Black Hills either! Custer State Park covers a lot of ground surrounded by Wind Cave National Park. One of the largest free roaming Bison herds in America lives here. Also Prairie Dogs, Bighorn Sheep, Mountain Goats, Mule and Whitetail Deer, Elk and more. Begging Burros gave Mom and I hours of entertainment feeding carrots, till one of them bit her! The Prairie Dogs also like carrots.
