That's pretty great! A tip of the pint.
In other news, in a scrumptious bit of irony, Willamette University has scheduled a talk for tonight: "Technological Innovation in Imperial Rome: What Can Ancient Concrete Tell Us About Roman Society?"
We propose a similar talk: Technological Failure in Post-Industrial America: What can Modern Concrete Tell us about Marion County Society?
Hopefully the County Commissioners will be in attendance...
