Nassau County voters rejected a referendum to invest taxpayer money in a $400 million overhaul of Nassau Coliseum and its environs. We’ll see what the Islanders do from here, I suppose, and on one hand it’s sad to think this could end with the club leaving for greener pastures. But as the son of a Nassau Community College professor dealing with the fallout from rampant budget cuts, I find it hard to get too broken up about the fate of a woefully mismanaged hockey team that can’t draw well in such a densely populated area.
