I can ' t drink Blue Moon , it gives me an incredible head ache . I guess it ' s something with the sediment or something ? <| sep |> Doubtful I think . They raise the flag all the way to the top before lowering to half staff , then raise it to the top again before lowering it at the end of the day . No flag can be displayed above the American flag , least not in ' MuricaAn invisible flag would be in the way and wouldn ' t allow you to raise the real flag all the way to the top Flying the flag at half staff leaves too much room for the invisible flag It sounds made up . Maybe somebody thought of it and spread that idea around at some point , but I don ' t think the tradition started or continues around that concept
