Howdy Pard!
When, and if, I get back to Illinois this year, I'll certainly invite you to hunt the place.
My great grandfather built two houses side by side. That must have been before 1900.
So far as I know, that property has never been hunted.
My grandmother sold one piece of property and my uncle sold my grandmother's place
shortly after she passed on. But considering the location and age of those two parcels,
I'd suspect they hold treasures that would be the envy of any detectorist on this here forum.
Ever been to Kankakee? That's where the properties are located.
I'd need to get permission, but betcha I can get that done pretty easily when I get back there.
Blessings,
M-Taliesin
