You could even go there at night and walk pretty much anywhere - even sleep there if you wanted. Wow, have times changed.
We used to pheasant hunt along the west side of the airport!
Occasionally the Chicago Coppers would stop by to ‘eyeball’ us and talk hunting/guns. 1970 early 1980’s
A popular hunting spot, more than a few black guys mostly rabbit hunting.
Also a good size herd of deer and many claims/stories about them.
Then with complaints about the deer on the runway, the deer ‘disappeared’, miles of new fence and signs EVERYWHERE; NO HUNTING.
