went to michigan 2 years ago. leagally you're allowed 2 lines, 2 tip ups, 2 rods or 1 of each. they had record high temps that week, the same week the guys got stranded on erie. my buddy hooked up with a guy who fished tournaments and he was catching walleyes. he said fish where there was still snow on the ice. the snow kept it darker.80 feet of water, the lake was 9 miles long and 4 miles wide. i don't think he was legal, he'd jig a while, then jump in his truck, and check his tipups across the lake. being mobile is easy when you can drive your truck to where you wanna fish. shallower water, fish in the snow drifts.
