You guys are so misinformed I grew up in northern michigan, "Yep I a UPPER" The kings are not all tules, In 1962 Michigan traded a large number of lake trout (what you here in washington call Mackanaw's) from the Mackanaw hatchery on the very norther tip of the sorthern part of the state for the kings,silvers and humpys that they catch up there today.) SO they are the same fish that we catch here. They are fine to eat the lakes are huge, and once you get north enough from the big citys you can drink the lake water, the bigest king I seen growing up was 74 pounds, The limit used to be 5 kings/silvers and 10 humpys a day. I have caught lots of limits, I think the limits of today are 2 kings/silvers and 5 humpys. Most fish are caught in the lake the people up there realy dont do much river fishing except maybe the ausable and a few lower michigan rivers....DJ
