I was flying at the local park today. Its a very drone-friendly park. I stay away from people and don't fly over them or events. I don't have a Part 107 and fly and do photos for myself. Today while I flying a Supervisor from the City came over and asked if I could take some Aerial Photos of their "Tree Chipping" Event and email them the pictures. Their were the city workers, the public there as well unloading trucks. Can I send these pictures to her without getting into any trouble with the FAA?
