Old K18. There's not much to say, ride it and you'll understand. The hills and terrain are the stars of this ride. Unending climbs, fast descents, open skies. But it's the unending vistas that will mesmerize you on this ride. Vistas near and far, all beautiful and serene. Just you, the open road, and the vistas. No cars, no other people; everything a Flint Hills gravel ride should be.
