The park rangers can get antsy when you get too close to the edge where it gets a bit "wild". I've had them yell at me over this. When I pointed out that I hadn't crossed their line, they got pretty flummoxed that I was not understanding their concern. That happened more when I was snorkeling rather than on Scuba. I used to teach there and loved the diversity. I didn't like the interference even when you followed the rules. Lesson learned? Thank them for their concern and never argue the point. Get back to diving ASAP and forget about 'em.
