🇺🇸 San Francisco, United States of America
San Francisco is a major city of United States of America. Real-Earth coordinates 37.784°, -122.400°, population 3,450,000. A river or a coast to follow, tall enough buildings to make a proximity line interesting, and open airspace once you clear the centre. Skydex flies the real Earth here — the elevation, coastline and city layout under the aircraft come from the same data the map does, and the sky is shared with everyone else flying it.
