Crazy side story of people drawing lines on maps without looking at lay of land.
The heliport near Skykomish is legally in a far corner of King Country, all roads to it go through Snohomish County.
(I don’t know if the heliport is active - decades since I was in Skykomish, nor who uses it - hopefully for emergencies in the pass helicopters can land at the downhill ski resort. which should have its own helipad.)
