The Pasadena (CA) city hall is one of the most photogenic buildings I have ever seen. I intend to use my quad to fly around it and take various video/photo views. There is a large, open space (concrete for parking on the edge and events in the middle) in front of city hall. There is plenty of room to launch a quad and fly it in this area alone. Close nearby is the Pasadena police department. I think you may sense where this is going .... As far as I can see or tell, there is nothing illegal about flying a quad in this area, provided it is done when there are no groups of people around. I would do it on a Sunday when there are not many people around. But I am concerned about the Pasadena P.D. I have seen a number of videos on YouTube involving quad flyers doing nothing illegal, but still being rousted by police officers who are unfamiliar with the rules for quad flying and who "just don't know about all this." I don't necessarily want to check in with Pasadena P.D. before flying because I'm pretty sure they will say no, even though there isn't anything illegal about doing it. Then I would be screwed. More better, I think, to just do it and deal with the cops if (or when) they show up. I realize that if they kick me out, I'm kicked out - even though they would have no grounds to do it. Any thoughts on the best way to handle this? Things to say to the cops when they show up? IS there anything illegal about what I am proposing to do?
