Sounds like an awesome trip. I would like to do the same thing on the North and South Forks of the Flathead in Montana. Take a look at some of the solar chargers. Maybe someone will chime in that has one.
Hey Mega bucks, what do you know about the flathead? I have been researching that trip as well for the past year. I looking into a DIY trip, found the packer that Yellow Dog and the local outfitters use for the 2 days horse back ride in. I've got the gear. I know its dry fly cutthroat heaven but the bull trout are what interest me the most. I'm trying to get all the logistics down as far as travel and fishing days go. I think you need roughly 10 days total to do the trip from the time you leave your house to the time you get back home.
