Atlantis Marine World in Riverhead, Long Island has many wonderful exhibits and is a fun place to spend the morning. I was particularly taken by the Shark Dive (shown above), where for $155 you can put on a wet suit and scuba tanks, get in a metal cage, and be lowered into the aquarium's 120,000 gallon shark tank. I passed on this opportunity, but took some footage of what it looks like from the outside. [NOTE: Only $140 for members].
