I was in Wisconsin this summer during a bike trip. Always amazed, but not surprised, by how the HD's really outnumber everything else there. I think most of of that ride BMW's are accustomed to riding a bit less common brand.
I rode from my home in eastern WA yesterday to Joseph Oregon for breakfast. Some great twisty mountain road riding in some beautiful country. I go that way quite a bit and for whatever reason, BMW's usually outnumber the other makes of bikes in that area. Yesterday I only saw two HD's, and they were parked in Joseph, two FJR's, two Goldwings, and about a dozen BMW's, of which more than half were GS's. The BMW's pretty much outnumbered the other bikes I saw 2 to 1. Always nice to see you other folks out on the road.
