Have you ever seen a feeding frenzy? I just got back from a Cruz to Catalina Island, in California. We went on one of those glass bottom boat tours. We got super close to some fish and the KELP was huge.
Basically what we did was we pushed a button from the inside of the boat that sent out fish food. That caused the fish to rush up next to the boat and push up next to the windows...of course. I am not sure I am much of a cruzer, but I would not mind going to Catalina Island again. We did not get enough time there. The kids had so much fun.
