Plywood fences of doom are not an unusual sight, but one with a big red sign on it that says "unsafe" tends to catch one's attention.
66-52 58th Avenue in Maspeth has been shut down for just about a year. It looked to be one of those "teardown - subdivision - huge pile of crap" jobs. Not sure what happened to the owner. But there apparently was a water main break last month and now it may collapse - along with neighboring buildings. More recently, it's been vandalized, which explains why the fence was wide open allowing this wide shot.
