Well, I'm personally biased towards the Mississippi River valley. The Hardwood Forested Bluffs really can explode with color from near the Twin Cities, down to around Dubuque, Iowa.

If you head farther north, there are limitless places, and you'll get a few more evergreen trees into the Mix. Up along the Great Lakes, Say the North Shore of Lake Superior between Duluth and Thunder Bay, The Apostle Islands in Northern Wisconsin, Pictured Rocks in the UP, or Door County, are all places with lots of good viewing opportunities.

And then of course, there is so much good forest land that sometimes you'll just run right into great foliage without trying. About 2 years ago, I was driving on just the right day to see peak color along I-90 near Wisconsin Dells. The Reds and Oranges were so brilliant, its really hard to describe.
