Mildred is on O'Fallon Creek 20 miles southeast of Terry. Not far from Mildred you can get on the Big Sky Byway in Terry. The north-south orientation of the Byway will give you a glimpse of dry land farming, rolling prairie grassland, scenic scoria buttes, and badlands terrain. While in Terry visit the Prairie County Museum and Evelyn Cameron Gallery. The museum exhibits capture the essence of the old pioneer life and The Cameron Gallery displays the pictorial works of Lady Evelyn Cameron, an Englishwoman who homesteaded in Prairie County in 1889.
