Hah!
That picture was taken by a friend on mine in Scottsdale AZ at the Scottsdale Rd and Shea Blvd... I think Mobil gas station. Could be an Exxon, I can't remember now.
I hang out at the Dirty Dogg Saloon (a biker bar) which is 1/2 a block from that gas station when I'm down there. He used to work as a bouncer there, and took that pic one afternoon on his way into work.
