Good thing I found this thread!
Hey jk, i was in Bourbonais/Kankakee last Friday. (Passed through, only was there for a short while). I saw the STH thats the north-most siren on your map and a couple of 2001s.
THe last time i was through there, back in mid March, i saw the Thunderbolt ontop of the college building, the Thunderbeam on Main St, and a 2T22 (don't remember the location).
I'm very surprised that they have their old system still! but who can complain?
Unfortunately, i didn't take pics
