Minneapolis is a fantastic city, for all the reasons listed above and more. As for the cold, it really depends on whether YOU can deal with it. Your kids will be fine - those of us who lived in the area as kids were totally used to it and usually enjoyed winter for the sledding, skiing, snowman-building aspects. And of course, the Twin CIties are filled with happily adjusted adults whose lives aren't "ruined" because of it. However, it is cold, and I wouldn't rule that out as a consideration, if you personally feel it would make your life miserable.
