ok hitting the retirement age and looking to snowbird in florida. thinking about marathon. how is the diving there? looking to stay under 100;ft , preferably 40 to 80 ft range. underwater photographer, i like macro subjects. dove a lot of the east coast from vero beach to miami area. dove key largo a couple years ago and was very disappointed. back in the 70s and 80s the reefs were really good. no so much anymore. with the covid hampering my over seas travel, looking stateside. any thoughts?
