Launched the boat at 7:00 pm and went down the Halifax from the Dunlawton bridge toward Ponce to a friends place. When I got to his dock there was a Manatee with a calf next to his dock. I tilted up the engine and just watched while they swam under the boat. The mother wacked the bottom of the boat just to let me know she was there. Awesome night on a very flat river. Going to back out as soon as I can.
