Oh. Wrong penguins. But obligatory penguins post. See: History of Hockey in Pittsburgh.
With obligatory historical musing. I learn from pittsburghhockey.net that a) Pittsburgh's only loss of a professional sports team came in 1929 when the Pittsburgh Pirates moved the franchise across the state to become the Philadelphia Quakers, and b) they used to play professional hockey inside Duranti's.
And the demolition of the Lower Hill District began on May 31, 1956 to make way for the Civic Arena. I suppose they can't possibly have demolition permits in place yet, but it would be some irony if they started demoltion on the same date. And what are we going to call it all in posterity. It was the Civic Arena for the vast majority of its existance. Will we call it the Mellon Arena even after it is gone? or reused I suppose. Mellon as a stand alone moniker is gone right? We never thought of calling it the BoNY/Mellon Arena.
