Are these the areas you're going to?

Black River Falls looks pretty sweet. I'd definitely like to get down there sometime. I don't know if Fort McCoy is the bombing range you are talking about, but if it is, according to that terrible website I posted above, the officials at the base are out to get as many citations as possible, even if you don't deserve them. I don't know if that is true at all, just what I read on the site.

Take some photos of whereever you go. I'm curious to see what's available.
