Scuba Lessons Inc. Co-Op Dive Club formally invites you to attend the Neptune's Memorial Reef 2 tank dive with RJ Dive Charters. This dive will be a Reef.org Fish Survey Dive Event. Neptune's Memorial Reef is designed as the largest artificial reef in the entire world, when finished it will be over 16 acres. Currently the site is more like 450 square feet but what is there is AMAZING! It is a mock up of the lost city of atlantis, complete with statues, gates, hallways and cooridors and thousands of fish to count!
