Three of us had a similar experience on Thursday going for perch. Started around G can (close to the honey hole) with 2 head boats nearby. Nothing. Can?t remember a time when the sonar had so little activity. We moved around. Nothing. Went near H can and caught 1 jumbo perch and 1 drum. I was reluctant to go farther out into the lake since the visibility was so poor. Agree also the black flies were terrible. Smoke, flies, no fish. It was a bad day.
