I've been away from SCUBA for decades, but I wanted to practice in somewhat safe waters. I thought about anchoring off rock or steel jetties in about 20' of water and getting wet again. Or, maybe even beaching in between them with my wife so that she could play too. However, a friend busted my bubble by stating that NOW since Obozo, no one can anchor closer than 500 feet from a jetty. Don't know how true that is so I thought I ask here.
