Check in to Montana. I have never been, but I think that is where we will end up this year. Flights are actually somewhat reasonable in to Bozeman ($400 from Detroit, probably a little more from NY).
If you're down with doing some trekking, fly in to Spokane and rent a car, you can be in BC interior in ~3 hours like Red Mountain, etc. again it's on my bucket list but never been, but I hear things like "tits deep powder" and "trees for days"...
