What an experience!!! You had the luck and skill riding with you.
Yeah, the FIRST time I used my GoPro+ LCD camera in salt water. I had it almost a year but when I used in the salt creek within a couple of minutes this manatee came into view. Luckily I had the camera running or I never would have had time to turn it on to record this. It was only running for about 30 seconds when the manatee came into view. I edited out the first part so it was manatee almost from the get-go.
