Absolutely no reason to go all the way to the west end of the Lake in Michigan if you are staying in Port Clinton. Plenty of good to great walleye fishing right there near PC in May. Once you arrive, just check the locals and here. If you trailer it anywhere, it would be east to Huron, but that's not necessary either. The whole area from west of the Bass Islands to the east side of Kelleys will provide you plenty of oppoutunity. You'll probably spend a good amount of time in the South Passage, or never more than 4-5 miles from shore or one of the Islands. Next week should be great as long as the weather cooperates.
