S California

 Last week we were on a short trip to Southern California.  We entered the state  on Interstate 8 after going through Yuma AZ.  We stopped for lunch at the first rest area.  It was a center rest area with both east and west bound drivers in the same parking lots.  Across the west bound lane was a set of sand dunes.   And then I saw some ORV's running up the dunes.  PICs below.
