I'll add that prior to learning about planer boards, dipsy divers, and suspended fish, that the only fishing book I had read was 'Spoonplugging' by Buck Perry. Our first year on the lake, we'd go out and seek out structure to fish around based on the spoonplugging book. The first trip we camped on Kelly's Island and I found Kelly's shoal and Gull Shoal using my lakemaster chip. Very good 'structure' This was in early August. I went to a local bait store and asked what I should use to troll for Walleye and left with an assortment of reef runners and advice that it was 'out of season'. I would set my depth finder/gps to highlight a narrow depth contour, say 13-15 feet and we would flatline two lines. I'd let them out till they ticked bottom and then bring them in a little so they're run clean and then follow the coutour around the reef. Believe it or not, we caught 5 walleye that day doing this and I'd wonder to myself why no one was fishing around the shoals. We literally had the place to ourselves. I could see a pack of boats off to the Northeast (perch fishing), but no one was around the shoals. I believe we were catching the 'resident fish' that you hear about but very few fish for.
