Hop on google maps and go into satellite view. Its the absolute best scouting tool for small bodies of water. My old man is the only person I tell about fishing spots any more. Thanks to the internet, the second you post about when/where you caught something, people take over. There's pan fish in every little puddle you pass. Start scouting now, anything that is park district for the most part will have park hours and rules/regulations. If there's no ice skating, there's no ice fishing. You really dont know if you're going to get booted from places until you try them. If there's not signage specifically prohibiting ice fishing or keeping off ice i dont know how else you would find out.
Get out to the city and fish the harbors once we ice over. You can spend a few hours on the ice and catch a hundred perch. Action and good eating. Its just a bit of a drive some times.
