Denver, Colorado or Salt Lake City, Utah.
Yes I'm serious. I've lived in SLC all of my life and I wouldn't want to live anywhere else. There's so much to do around here with the canyons and lakes and stuff, it's not even funny. Night life isn't quite as large as other cities, but it's not bad either.
And waking up and looking out your window to see Mountains everywhere covered in snow is just awesome.
