Drove out to Portland from the Midwest with a friend once. I also denied Wyoming's existence, but after seeing it I gotta say it's too beautiful to deny. Idaho though? That state did not exist, like the PNW's Bermuda triangle.
Nature is great in Idaho. It's the people there that suck; bunch of Mormons, Far-Right Catholics, and Aryan Nation compounds. There's a town named Athol we joke was named by a fellow with a lisp describing the residents.
If you want to enjoy the best that Idaho has to offer go to western Montana.
