Barn quilts seem to really be getting to be a "rage"...there are 9 counties in Wisconsin where I live that are noted on a map where you can see where all the barn quilts are in that county. Many other states also have maps. Here is a link to where you can find out where the barn quilts are in your state...at least the ones that are registered.

I have seen many of the ones in Racine county and hope to do another barn quilt "tour" someday.
