Heading up to grand rapids next week for xmas. Hoping to get the kids out of the house and on some ice. How far north of GR do we need to get to find safe ice? I really don't care about catching or great fishing, just want to get out for a couple of hours if possible. If I could catch some fish that would be a bonus. I see they are fishing in Cadillac but wondering if there's anywhere a little closer. Tha ks in advance!
