What to Do With the Mellon Arena?

PopCity: "This is an emerging story, one that will gather momentum this September as the city enters the Master Planning phase of the its most expensive piece of available real estate: the 28 acres of the Lower Hill.
With the creation of the new Consol Energy Center, 2010 home of the Penguins, the current Mellon Arena will become obsolete – and destined for what?
Some say its an eyesore, a white elephant, a symbol of the failed 1950s urban renewal efforts that should be demolished – as were its late cousins, Three Rivers Stadium, Pitt Stadium, and Forbes Field.
Others say, no, the building is an engineering marvel, a symbol of Pittsburgh pride and achievement, and should be preserved, re-used, and will serve as a celebration of its past and the neighborhood in which it stands."
