During a recent drive-about, I saw a sign next to a proud pile of rocks. The sign said: "Recycled Rocks". As opposed to what kind of rocks? Non-recycled rocks? New Rocks? That got me started on a think-about. Wouldn't all the rocks we have today be from the Stone Age? Has someone been making post-Paleolithic rocks? As I recall from my college Rock-n-Roll 101 class, it goes: Stone Age, Bronze Age, and Iron Age, which are all followed by the Age of McDonalds, the Age of Walmart, and the Rise and Fall of Tiger Woods. I probably just answered my own question. Of course, it must be Walmart that is now producing and selling new rocks, at prices that we have not seen since the Stone Age.
