On your way to Sew n Save in Racine stop at O &H Bakery for REAL fresh kringle. They are on Hwy 11 also -and the highway is 31 (Green Bay Road) not 131. They will be on the north side of the street after the second light from Hwy 31.
House on the Rock is a bit of a drive from Chicago and is not in the SE Wisconsin area. But is neat to see if you have the time. There will indeed be dairy farms in that area. Mill House Quilts is also in that area of Wis.
SE Wis itself is pretty much an urban area. (Kenosha - Racine - Milwaukee counties). Go west or north of Milwaukee to see farms.
Cedarburg has all kinds of shops besides the quilting one mentioned.
