    Please DO NOT turn your trailer up the main road to the ranch, on the North Side of Highway 20! The main address of the ranch is the only address we have for the ranch. Our Horse Motel is on the South side of Highway 20. If you go up the main road to the ranch there is a strong possibility you may need to wait until all of our horseback riders mount or dismount from their horse riding tour. Also, turning around at the main ranch can be a challenge, if we have a lot of parked guests at the ranch.
