I see the weatherproof tubing of an electric meter behind it....is it in service?? Did you get a Pepsi from it?
Well, it's not the most secure place for a soda machine, but if the owner isn't concerned about it, I say more power to them.
EDIT: It even has a street lamp there, that appears to be for the machine. Would it be a scream if this location was actually sold to the owner of the machine?
EDIT 2: Now that I think about the photo some more, there was room for another soda machine on that slab. I sure hope it wasn't a Choice Vend.
EDIT 3: The road surface changes right in front of the slab. Was this at a county line or something?
