The year is 2099. Two archaeologists are scooping dirt at a dig in the northwest part of the United States. Suddenly an arm freezes. One of the archaeologists has hit a solid impasse. Excitedly they both clear the dirt away and uncover what looks like a part of a cinder block wall.
One of the archaeologists is puzzled. He asks, "What do you think it is?"
His partner carefully examines the exposed cinder block. Then he responds "I'm not sure. It looks like part of a regional shopping mall."
"A regional shopping mall? What's that? And what happened to it?"
"Ready for a little history?"
"Okay, but please, brief and to the point."
