I'm working on some plans for a fall moose hunt with my dad that is going to have to be completely self guided. I've hunted quite a bit up here and have my fair share of boat experience. I'm wondering how difficult is navigation of the Tanana in September? We should have an 18' boat with a 100hp Honda with jet lower. We will be looking to get up to some of the sloughs then foot it in to look for a moose. Any advice would be highly appreciated.
