Grand Piano Found on Sandbar off Miami Coast It sits in Biscayne Bay ... and authorities say they won't move it By Kate Seamons, Newser Staff Posted Jan 25, 2011 5:55 PM CST 23 comments Comments A U.S. Coast Guard boat passes near a grand piano on a sandbar in Biscayne Bay, Tuesday, Jan. 25, 2011 in Miami. (AP Photo/Wilfredo Lee) (Newser) – It's not exactly sunken treasure, but it's just as mysterious: A grand piano has appeared on a sandbar off the Miami coast. Weighing in at 650 pounds (or more), it sits at the highest spot along the sandbar, which keeps it from being submerged during high tide, reports the Miami Herald. Authorities aren't sure how it got there—and they have no plans to move it. "Even a car can become a habitat for wildlife," says a Florida Fish and Wildlife Conservation Commission rep. "Unless the item becomes a navigational hazard, the Coast Guard would not get involved.''
