I'm not sure about clinton, but perry went from 15 percent ice covered to nearly 100 percent in a few days. I would imagine it would be a bit before we are able to safely walk on them. Now the smaller lakes you mentioned might be ready soon. I have been anxious for some good ice also. I mostly fish from different docks through the ice, but if it got thick enough, I think it would be a blast to hit my usual brush piles.
