San Carlos is East of Globe AZ which is east of Phoenix.  Vulture gold mine is near Wickenburg AZ which is west of Phoenix.  They are about 75 miles apart crossing straight through Phoenix to get there. There's probably a dozen airstrips if not more between these two and not sure if Vulture strip still operates or not but it would be a tiny strip if it does.  Vulture mine is just a tourist attraction ghost town. This sounds very far fetched.
