Awesome pics! Some of the underwater ones would look great blown up and framed!
My girlfriend Cathy, lives in Crystal River and when I was there several years ago, we went kayaking to 3 Sisters springs to see the manatees. The water is so crystal clear and beautiful! A little chilly for me tho. But we had fun following the manatees thru the canals back there. We could identify them by the propeller scars on their backs
Next time I go back, I want to do snorkling with them.
