Was thinking about flying over lollapalooza music festival in Chicago. I was there yesterday and i think some aerial footage would looks pretty cool. Just curious if this would be legal? I dont plan on getting close to the crowds or anything and am hoping to have it high enough where its not too noticeable. And i would be flying it from outside the festival. Also do you think that many people in such a small place with all their cell phones and stuff would interfere with the quad or fpv?
