I don't remember, but the meter socket enclosure was on a pole at the corner. I was being observed by some local people, and they must have wondered why I was taking the picture!
It probably was a zip cord going into the top. Zip cord is not uncommon in these streets.
The traffic light -- I don't need no stinkin traffic light!
I will search my archives, because I may have another picture from another angle.
In the meantime the wires may have been removed (stolen) so they could be turned into cash!
