From my experience when guys find em’ their lips stay shut. I will tell you that I saw a monster eye’ swimming off the docks at Maynards last week! He was all of 30″ long and was with a couple monster carp…You could start there!
I don’t fish them out there but have a buddy who does. He only fishes them at night and says he fishes areas with artificial light on the water. Meaning areas that street lights or dock lights reflect on the water. Apparently the baitfish school up in these areas which attracts the walleyes.
