Giant Mike - Do I remember correctly, w/o googling it, that the Rock River is the same river that flows through the Dells? Do they have concerts in the same location, more or less, as the recreation? I think the monkey was lost with the foreground ladies bustle!
Since he didn't answer...
I am 99% positive, without looking at my atlas in the car, that the Wisconsin River flows through Wisconsin Dells, and the Rock River flows through Waukesha County, just a few miles west of the Milwaukee city limit.

Finally got to see the images. Very neat!
They should try this with (some) other famous paintings.
