Minocqua is a nice area. Im a little over an hour drive south from Stump Shot. About an hour south of me is Wisconsin Dells. All the outdoor water parks will be closed by then, but they have a ton of indoor ones, my family has been to most.
The upper dells boat tour would probably be pretty cool as the trees should be changing.
My girls, my oldest, being a goofball as usual.
You stop twice. Once is a short walk through a rock cut. The other stop is to a rock pillar that a German Shepard jumps back and forth off a bluff.
Minocqua and the Dells offer alot of the same stuff.
West of Madison is Cave of the Mounds. Guided tour through a cave. Both my girls have enjoyed that.
If you come through Wisconsin and wanted to avoid Chicago, you could always hit Hwy 51 south out of Rockford and then cut west further down, even cut west through Kentucky.
