Boise area, Denver area, Dallas-Fort Worth area, or the Salt Lake City area
Michigan is what you just described. In central and northern michigan you get 75-80 degree summers and 10-30 degree winters. 1-3 times every 2 weeks it rains or snows and the trees get pretty colors for a month or 2 in the fall. Sometimes we get dark overcasts that can stay for a couple days though. And don t get worried about the security because of Detroit.
