Our "tour" of lost pro sports venues continues with another stop in the Keystone State, this time for a loving look back at the life and times of Pittsburgh's legendary Civic Arena - aka "The Igloo" - with Steel City native Dave Finoli (editor, "Pittsburgh's Civic Arena: Stories from the Igloo"). Originally constructed in 1961 for the city's Civic Light Opera, the Arena was an ahead-of-its-time architectural marvel - distinctively adorned by a massive 3,000-ton retractable steel-roof dome that was world's first of its kind - making not just an attractive venue for music and entertainment, but big-time sports of all kinds. Over time, the Igloo became synonymous with its longest-running tenant - the NHL's Penguins - who became the building's main occupant as an expansion franchise in 1967, and saw three (of its total five) Stanley Cup title runs. But, of course, we remember the other teams that also called the Civic Arena home - including: basketball's Rens, Pipers & Condors; World Team Tennis' Triangles; soccer's Spirit & Stingers; arena football's Gladiators; lacrosse's Bulls & CrosseFire; and even roller hockey's oft-forgotten Phantoms. And don't forget Dr. J's Pisces too!
