Well, this is the strangest thing.
I am digging on the Heifer Village & Urban Farm posted by an anon that suspected a link to a keystone (along with Opus One and Buck Palace).
I cannot make the flightpath shape fit the map BUT there is something really strange about the layout of the place as there seems to be two different axes for the layout.
Attached is one with white lines that indicate/match what looks like the obvious centre of the place and then the orange flight path lined layout with a different axis. The reason why I say I can't fit the flight path to it is because it just won't fit ANYWHERE. It's close but no cigar that I can see. Maybe I'm just being too exacting - I dunno.
I will attached the screenshot of the untouched map, a png of the orange flight path which you can copy and place over the map to see if you can match anything, a graphic to explain how I converted the flight path into the orange shape, the map with the white lines converging on one point, the map with the orange flight path and the map with the combined white and orange lines.
Have at it anons.
Note that the dark area is not a part of a building - it is the shadow from the white circular building.
