You can also hunt Medewin Tallgrass prairies which is a neighboring property t Des Plaines conservation. Before moving to Texas[:@] I hunted both of these places. Saw HUGE deer at both places. Last year in Medewin I saw three deer over 150", one being a 170+ typical. Lots of land out there for these deer to get old and big.
To hunt medewin you need to go to their offices on Rte 53 and pick up a parking permit and map. Check out parking area three...had good luck out there. Good luck. Naperville is about 30-40 minutes for Des Plaines Con. and Medewin. Thats where I lived before I moved to Dallas[:'(]
