Had the USAF gotten Viggens, we'd have had to check the road for jet traffic before proceeding.

E. Montana was/is a low-level training area and has a population quite amenable to those circumstances.
Can just see this conversation at Randy's Restaurant in Plentywood, circa 1982:
Farmer Bob: "Hey Joe, I got Steved again today!"
Farmer Joe: "Y'did?"
Farmer Bob: "Yep. He'd landed his plane again on d'road an' blew over her flower pots. This time he didn't stop for coffee. D'ey must be pretty busy t'day." ^_^
Farmer Joe: "Ja. (with pride) Us Scandahovian types build a pretty good rig."
Note: Steve Brekke grew up in NE Montana and then trained in his F-106 right over his own dad's farm and would routinely buzz tractors in the field. It was known as "getting Steved."
A Viggen in New Blue or Grape Aggressor markings would be cool too.
