I grew up not too far from Palos. But no, we drove out there to check out some of the sloughs and doing some bicycling. We bring some photo gear as well. This week we only got a peregrine falcon at Saganashkee Slough.
We were also looking for the nuclear reactor sites from WW2 bomb making. We had been there before, but wanted to check them out again. That's where the first nuclear reactor is buried. Most of the facility was removed and returned to forest land, but you can still see some old remnants.

It's weird how it all seems like natural forest and ponds, but you come across buildings and old roads in the middle of the woods. And all of the ponds are manmade. If you look up old aerial photos, you will see that the ponds and sloughs used to be farmland. The dug them out to use the fill material to build up the expressway system.
