I like to snorkel, but occasionally it can be weird and otherworldly. One time Richard, Russell and I were snorkeling off the coast in Puerto Vallarta, Mexico when we suddenly realized that we were swimming right next to a massive, solid wall of fish that stretched in each direction as far as we could see, with a barracuda right in the middle of the pack. It was startling and freaky to see so many fish tightly packed together, moving past like a big wall. This video reminded me of that experience.
