I was wondering what the consensus was on Long Key SP...... I have researched here and elsewhere and find that it is apparently a well liked park. My questions I guess are how long in advance do I need to reserve? How close are the sites?( I know only what I have seen in pics and the park map, which have been prone to be not so accurate and/or misleading) How is the beach at the sites? Can you fish ( and CATCH) out back of the site? How kid friendly is the park?
