i need a walleye guide

Hey Birddog, you are from the UP. My kid brother married into a "Yooper" family from Calument. They go out on the big water and bob for lakers & fats and he really does know where to get the nice brookies but he can't seem to get a lead from them on the walleye's. VERY tight lipped bunch he thinks!!! He's tried to weasel info out of them at family parties but he can never remember what they've told him when the party breaks up 3 days later!
