geography nerd that I am....and with @Charlie's very helpful hint.......I found the corner (Beach and Hwy 111) on Google Street View just northwest of Niland, CA.....the big tree in the Street View (link below) is creating the shadow in the late afternoon picture of the guy hitching (walking the roads of the Coachella Valley apparently firms up one's butt!)......the 8400N address is based on a 0 starting point in either Brawley or El Centro.....the mountains in the distance are probably the Chocolate Mountains, east of Niland......the link here is safe......yup, I'm a nerd!!.......
