So I am bringing my DJI Spark to Chicago hoping to film Lake Michigan and the Downtown Chicago Skyline for a cinematic video. Do any Chicagoans know good places to take off and get some decent footage without too much metallic interference? I would hate to see it go into Atti Mode and have a mind of its own and go awol. All of us Spark users know what will happen should it lose GPS Signal. I am going to be low key about my flying and not fly over large groups of people. All suggestions are helpful in my decision making and thanks for your time.
