A small concrete monument marking the Oklahoma–Texas state line set against flat Great Plains, offering minimalist compositions with endless skies, long straight roads, and dramatic sunrise/sunset color. Easily reached by car via a rural gravel turnout (no fees); bring water and dress for wind. Best light: golden hour and blue hour for rich skies; nights are excellent for Milky Way shots due to low light pollution. Limited amenities and parking — a short walk from the roadside marker.
