It's gorgeous out here, but house prices have shot up in the last several years, plus houses are scarce in general due to the Navy bases having more people stationed there than they have housing available, so the military families have taken nearabout all the civilian housing in the area -- at least on north Whidbey. Who knows though, you could get lucky. It's worth a shot!

Can confirm, we live directly under the flight path. You can't hear anything when the planes are flying, especially the Growlers

There's Colonial Creek Campground on the shores of Diablo Lake. We've stayed there a few times (and we consider it a "fancier" campground since it has water spigots and flush toilets; we usually camp where there's only vault toilets and we have to pack in our own water). Also around an hour east of Diablo Lake and on the other side of the pass is Winthrop, a cute Western themed town.

Maybe they were in a plane that flew over it?

Hey Mount Vernon's my hometown haha
