Nope just get JDR to move in at cove 2 and hawk all the divers and those who are in violation of the rules get slapped with a fine or community service. People are just going to do what people are going to do and the only way you'll get their attention is hurt them where they might care, their pocketbook.
So Uncle Pug, how about deupitizing JDR and any one else for that matter.
Sorta like: "Let me, let you, let me continue to dive at cove 2;" because if I didnt I wouldnt be able to dive cove 2 because you let yourself cross that line.
