"Sun Valley has always been a sleepy community along the old western highway of Old Route 66 and the newer Interstate 40. Not much is known about the settlement and how its roots began as a community, but it has and still remains largely rural and sparsely populated. Cattle Ranching has been one of the largest agricultural activity in the area. There are still some large tracts or ranch land around Sun Valley and cattle roam the open range of the landscape."
