Judging by the font, the real Superstore began claiming "Low prices every day" around the early 80s.
Some "whatever happened to..." speculation about Superstore here. (I think we all know what happened. Its initials are W-m.)
Speaking of no trespassing and Bum Town, I was on the ground lining up this shot of feathers found sticking out of the pavement...
...along came a drifter with his wolf-dog, saying, "That's my home!"
We assured him we were just leaving and we hadn't touched anything, and at first I was even nervously trying to explain the shot I was taking of the feathers. But he seemed happy for the company.
He asked us if we'd ever been homeless, turns out it's not that great, he said, and he asked my co-explorer Deanna if she would take him home with her, even though she lives in Maryland.
He got 53 cents out of our visit and gave us a parting gift.
"Don't you need this?" asked Deanna.
"No, I got my Bible," he said cheerily.
