I have no idea where they're heading. These are Florida Leatherbacks and they can be pretty heavy.
I stopped to save a turtle once and it turned out to be a snapping turtle. I hunted up a stick so I could scoot him hockey style across the road (he was right in the middle of the double yellow). As I was walking back to him with a stick I saw some a$$hole eyeing him up, and going out of his way to hit the turtle...which he did. If I even encounter that gentleman I believe I will drill a hole in his femur, attach a cinder block to his leg with a piece of piano wire, and take him for free boat ride...just cuz I'm a nice guy.
