Still find it stupid, because if drone doesn't make something harmful while flying, then the drone user shouldn't make something harmful, too.Yes FAA in US,. They ONLY control airspace. The OP's drone did nothing wrong and is ok to be in the airspace it was in. BUT the drone did not get the ticket. The OP WAS flying in the park, standing on its property. It was clearly posted at the entrance, the OP even posted a picture of the sign he ignored.
And I'm talking about logic.
