Add this to the long list of strange objects found floating in the Hudson River over the years. The Marist College rowing team was practicing earlier this week when the coach spotted something floating near the river's west bank. He hooked a rope to it and towed it to the team's dock on the east bank. What is it? A 7-foot-tall replica of a man's head made with Styrofoam and fiberglass. College officials believe it's a theater prop, but so far no one has come forward to claim the giant head.
