To answer your question, out yesterday saw 3 other boats. 2 docks are still in at the metro, but I would check the camera. I was surprised they were in yesterday.
1 possible rip (board slid back/and to the side, no fish when we got to the rod), no fish in the boat yesterday. Hit U-bay and the river.
Ice will be early this year from what I saw. Highest water temp was 33.8, 32.3 to 32.8 most places. Any serious cold snap now will ice up U-bay and the edges of the river.
Best part was trolling the wake of a 300' coal ship. My partner mentioned they fish the wakes of the big boats on St Claire so I thought I would try it. The power of the prop is insane. They yelled at my partner to sit down just before we hit the wake because it would jerk the boat and throw him overboard. It moved the boat like it was a cork. Any musky around would have had easy pickings, the shad were pushed all over the place. Gulls were picking them off behind the boat at will.
