Had a great time snorkeling today with Sundiver. A big storm is coming in, and Captain Joe and Mate, Justus kept everyone safe. We were given clear instructions how to navigate the reefs. Justus also gave out some delicious food recommendations. At the reef, I saw a myriad of parrotfish including the largest Rainbow Parrotfish I've seen. There were also some Great Barracuda swimming around.
