There was a concrete plant near my house. A sign at the exit, directed towards truck drivers leaving the plant, read "Remember, when you leave this spot, YOU ARE Century-Crete." I always thought that was a warning to trespassers - if you fell in the concrete-mixing vat, there was no mercy. You were now a part of the concrete.
