Confusing signs is a fact. Two years ago, we were running here in the St John's. I was in an idle zone that was at least two mile long. There was a water cop behind me all the way. He could see I was trying to obey the law. After a couple miles, I came to a sign that on the side I was looking at said "Slow Speed". When I got where I could see the other side, it said "Idle Speed", which I'd been doing for a couple miles. I assumed that slow speed meant the 30 mph speed limit on the river, so I hopped up on a plane. As soon as I did, Debbie said, "Here he comes". He pulled me over, and I explained about the confusing signs. He wrote me a warning. I've yet to figure out why certain parts of this river are idle zones for the manatees, while others aren't. It isn't that wide of a river. I think manatees like big houses with dock apparently, because that's where the "Manatee Zones" are located. Maybe Manatee is an old Indian word for "Big Dock".
