No doubt big pike. Common sense works up north… However, the big lakes on the madison chain sometimes they don’t freeze all year other years they only get marginal. You’ll see some dumb shite out there on 4 inches trying to use a machine. This last year I had a guy go through on Waubesa on his snowmobile almost took me in with him. I was on 3 inches barely. Ever hear someone scream when they thought they were goin to die? Lucky it was only 4 feet deep. The sheriff got tired of mounting expensive rescue opps for people too dumb to know what they were doing.
