These are the carnivals I can find for villages during the July 3-July 6 week. However, Morton Grove is from July 2nd -5 so be aware of that. These are all in IL though. Some of these carnivals have websites while others don't.
If a carnival has multiple units (unit 1, unit 2), that means that the rides from those websites are at multiple places. So, if you want to go on a Zipper, the carnival may or may not have it if there are multiple units.

Naperville Ribfest
They have the other half of Spectacular Midways. They have the Music Fest here. Probably the 1st unit.
Bartlett Festival in a Park
They have fireworks, and the weird Astro unit with no Spin Out, but yet no Himilaya.
Lisle Eyes to the Skies
They have All Around Amusements.
Crystal Lake Gala
They had Wilson Family Shows.
Mount Prospect
They had Fantasy Amusements without 1001 Nachts, and Tilt-A-Whirl.
http://fantasyamusements.com/I'm guessing that Dixon (Petunia Festival) is the other Astro rides. It probably has a Himilaya, and the Spin Out.
Some carnival is in Kirkland.
