I saw northern lights one time in Idaho. they were green, but nothing quite as extravagant as what is pictured there in that photo.
Definitely Utah, perhaps Canyonland with the snow capped Manti La Sal in the background. I use to live in Utah
I really love Maine, spent some time up there when Bush Sr. was pres. I was there when Kennbunkport was hit by a hurricane, crazy! The Bush compound was hit hard.
