Irm kayaked out to the reef across from Xanadu to snorkel. I am still kicking myself because I decided to stay behind and lounge around the pool. He was just snorkling around and all of the sudden there it was. Irm said it must have been 10 feet long. He is 6'4" and it was much larger then him. He feels very very fortunate to have had that encounter and a camera with him. Very very very cool.
