I did see a small shark in Shark River once, something like the resorts that have a whaleshark on their website, they saw one once but a great white in Shark River would sure clear out the OW students! :)
I was going to ask if you wanted to do Shark River Sunday evening, I think high tide is 6:30pm, the water and air should be about the same temperature and we could see if the seahorses are still there or went to warmer waters.
