I am floating from sportsman to skilak next week and i keep hearing about this back channel between river mile 72-73. I have only floated the section from the ferry to jims once so i am going with a friend that has more experience than me and he says he usually takes a back channel that exits across from jim's landing. Is this the channel that everyone says people should avoid? I cant find a good map with the river miles listed to try and determine this myself. I will have the wife and kids so i dont want to take any unnecessary risks until i get more comfortable with the river.
