While CR S-7 ends at the entrance to Palomar Mountain State Park, a very narrow back road, Nate Harrison Grade, leads from the park down toward the valley floor. This road is not a good choice for most vehicles due to the narrow roadbed, extensive unpaved segments, and occasional closures for weather, fire or other reasons. Photos taken 06/16/06.
