Western vs. Eastern

Just by looking at a map, I noticed a big difference between Western Montana and Eastern Montana. Western seems more populated and more mountainous. Eastern is more flat and not as many towns. From what I hear, Eastern gets colder and windier. The snow is dryer and so it doesn't stay on the ground too much. Western has wetter snow and less wind due to the mountains. I love the mountains, and would appreciate milder temperatures, so if I had to move anywhere in Montana, it would most likely be on the Western side. I am not sure what the summers are like in these areas, but plenty of people have lots to say about the winters so far.
