I was up on Lake Mitchell and Cadillac 2 weekends ago. Good ice, about 7 to 8 inches. There were snowmobiles and 4 wheelers on Lake Mitchell. I would call the bait store on Lake Mitchell, I think it is call the M-115 bait store. Nice, knowledgable guy answers every time I call.
I hope to go back up to Mitchell this weekend, myself.
