We were motoring along the ICW a few years ago in the fog. I could see about 100 feet. We're looking at the radar and I see this target coming at us. I was watching it and it was coming at us fast. As a wild guess I told the Admiral that something was coming a us at high speed, about 30 miles an hour. We were straining our senses forward and couldn't see or hear anything. I looked at the radar and there it was now only a hundred yards away and coming at us fast. ( it was like a scene out of Forbidden Planet ). IT'S STILL COMING!!!!!!!.
With no place to go I took one last look at the radar and it was a couple of hundred feed from us moving fast. We just looked forward and then up and saw a flock of birds flying overhead.
Damn!! Freaked us out.
