I have been with Nurse Sharks before, sail boat ran aground on sandbar, nice nurse sharks all around while pushing off. My first experience near a shark, so graceful yet the way they move yet it makes such a statement, like "I am the most confident swimmer in the ocean!". The most freaky experience was my first one snorkelling in the keys on New Year's day, a friend helped chum the waters that day! But besides that, after my first experience snorkelling, back at the boat, my friend exclaims, wow! did you see all the barracuda? What do they look like? I say.. After the description, I realized that I was diving with dangly, silver earrings! Generally, I was a huge fish lure. Live and learn!
