A short drive north of Vernon lies a humble adobe building that remains a touchstone of the Texas cowboy culture. In 1881 the first Wilbarger County settlers, the Doan family, built a store and home near a low-water crossing of the Red River. They catered to cowhands herding longhorns up the Great Western Trail, America’s longest cattle trail. Doan’s Crossing proved the last chance for drovers to get mail and supplies before entering Indian Territory. Each year since 1884, the public celebrates that trail-driving past at the store with a May Day picnic, the state’s oldest continuing event. A granite monument boasts famous ranch brands.
