Depeding on how far from the interstate you want to travel, Moraine View State Park is another top notch park. Lots of shade, clean facilities. It can also be found on the IDNR webpage. Which routes are you traveling to get to alanta? We make the trip north twice a year for wifes family, they live over by St. Cloud(you betcha!). Be careful around Rockford, they are redoing the tolls to make them more open. DO NOT arrive during peak drive times, or you will be waiting 1-hour or better to get through.
