I had a few days to spend in Fort Walton, FL and was looking forward to a brisk swim. When I got to the beach, no one was swimming -- which I found very odd until I looked into the water and realized it was swarming with Jellyfish. I don't mean one or two... it was comical just how many there were. It changed my plans a little. Since I had a wetsuit, snorkel gear, and an underwater housing for my camera with me, I chose to swim in the jellyfish fields.
