What is the commonly accepted boundary between the Upper Midwest and Lower Midwest?

I -80 is a pretty good estimate for upper vs. lower Midwest. Minnesota, Wisconsin, Michigan and North Dakota, and South Dakota are never considered lower Midwest.

Do you think Missouri, Kentucky and Kansas are Midwestern states? Some people do. Some people don't. If you include them in the Midwest, then your definition of lower Midwest expands.

Here are some additional considerations: does the place have a Waffle House nearby (lower MW)? Is snowmobiling or cross country skiing popular there (upper MW)? Is sweet tea served at restaurants and cafes (lower MW and South)? Do people have a big city Chicago/Detroit/Milwaukee/Cleveland type accent (upper MW)?
