There are several barn quilts in central Illinois and Iowa. I never really thought about people not seeing them. Like everything else, when you see them all the time you kind of take them for granted.
Here are a couple of links to self guided tours in IL and IA. The second link is to a tour in IA. The barn on the first page of the link is featured in Eleanor Burns new Barn Quilt book.

These are in WI. I've never seen them, but they look pretty.
