Hey guys, I've been a long time lurker no this forum and finally decided I am capable to fly a phantom to enjoy and record some beautiful aerial views. Flew my first flight today at a public park, got many people's attention all positive asking me where I got one, how high it can fly, and it being awesome and cool. Until, a park security came over while I was bringing her down telling me I can't fly without a aviation permit due to invasion of privacy and endangering kids. To my knowledge public parks are just that, public, and me doing most of my flying out in the lake was not endangering anyone. I politely asked him to show me a pamphlet for the park's rules and policies stating the rc quadcopter (he kept using the word drone) is not permitted and I would gladly stop and advise my fellow rc friends as well. He failed to deliver of course, and stated that it is not formal and not written, but rules are always changing. I advise him I was flying in the lakes and kids are everywhere no matter where I'm flying (there was literally 3 kids at this huge park), at least I'm not flying around congested neighborhoods and peoples' backyards so I don't see where there was an invasion of privacy. He said I can speak with his supervisor to which I replied, "Yes please, I would love to learn about the rules so as to not overstep my boundaries", but he failed to give me that number as well. He asked if he could take a photo of it with the remote and asked for my number, which I was more than pleased to do and again I added, "I'm here to help and this is recreational, so definitely show me the park's guidelines and restrictions so I know to educate myself and my fellow rc friends." He said it's no issue, no problem..and just walked away. Sorry for the long first post, I just wanted to defend our grounds and rights as recreational flyers that are abiding by the law and I'm well aware to not fly in no-fly zones (airports or governmental buildings) and national parks, but seeing that no one there had a problem except this park security really picked at my skin. What do you guys think? Did I do the right thing?
