What do you mean "Midwest" tour? You mean from town-to-town, or even state-to-state? How many ponds? What an ambitious tour!
Here in Houston, our major pond tour is spread over three counties, but basically all in the greater Houston area. About 15+ ponds Sat. and 15+ ponds Sun. It's a LOT of driving, and, even going ninty to nothing, you can't make them all.
But soooo fun! And you learn so much, come home all jazzed with new ideas, and get an eye-full too boot!
