Now reviled as dilapidated and obsolete, the Nassau Veteran's Memorial Coliseum nevertheless has a proud history, though much of it belongs to the rapidly fading past. The NHL's second-oldest arena (after neighboring and newly renovated Madison Square Garden) cost $32 million to build and sits on the former Mitchel Field airbase. It hosted its first event (a New York Nets ABA hoops game) on Feb. 11, 1972. The following fall, the expansion New York Islanders took to the ice. They've called it home ever since, but will be moving to new digs in Brooklyn in 2015.
