A few years back, I was bow lookout on a sailboat coming into Block Island's Great Salt Pond in a rain squall. We came around the jetty and I spotted the nun bouy [which had an distinctive reflective wrapping on its top] and shouted back to the captain: "Come to port! Either that's a nun bouy or the biggest damn bottle of Miller's I ever saw." We stuck in the mud but it was a rising tide, so we came off a couple hours later.
