If you would like to live and raise a family in the US, where would you live and why?
There are some prerequisite conditions:
At least 50 miles away from any major urban center.
Must be within 20 miles of a river or lake.
Must be within 20 miles of a interstate highway.
Must be within 50 miles of a business jet-capable airport.
This is serious (you might be rewarded).
I once visited an aunt and grandma that lived in Kellogg, Idaho. Cute old town. It feels like the world is in for hard times ahead, and being a few steps removed from the chaos feels like a wise move. As a place to raise a family... well I am of the opinion that raising a good family is mostly a matter of not letting other adults raise the children. Be involved in the kids' lives more than the school teachers, but also give them enough leeway that they can come in the house with scraped knees every once in a while. Speaking from complete ignorance here, though. :-p
Spokane is about 70 miles to the west, and a whole lotta nuthin' to the east. But the settled area stretches out pretty far, turning into Coeur d'Alene (pop 50k) as it crosses the Idaho border. That's about 45 miles from Kellogg.
Looking at some maps, there is some lakes and a river nearby, but I didn't visit those so can't vouch for them. And they are mostly in the direction of Spokane. For other amusements, there is a ski slope called Silver Mountain Resort. If you're thinking more along the lines of "emergency water supply", it looks like there are dozens of creeks and gulches in the region.
I90 runs right through it.
Dunno what accommodation a business jet needs. There is a small airport at the town, but I would be surprised if it is what you're looking for. Coeur d'Alene has a larger airport that really pushes the 50 mile boundary. Jet traffic is not non-existent there, though.
