I have a camper in Mack's Camp by Truman lake. I go down 5 or 6 times each summer fishing for flatheads. I have heard of a rock quarry on Truman that guys really do well in. I would like to know where it is located and maybe a little more about it? My flathead fishing hasnt been the best and I am going to start going a little closer to home here in north MO if it doesnt pick up. Any help would be appreciated.
