Me too, Ripp - but like BC, but Montana, being considerably smaller and having it's diverse landscapes into smaller chunks, I guess.
I suspect a bunch of this was filmed in Glacier National Park, Northern Montana - the upper part of the park runs up into Alberta and there, is called Waterton National Park. Breathtakingly beautiful and most of the park is "State's" side.
Ripp - you need to take your family there where the kids are large enough to appreciate it.
