In a dream: middle, main, lower, all the way out to heller. That is a Grand length trip. If I had the time and opportunity I would do it in a heart beat. As a side note, if you want to make something like this happen, contact Mi'chelle at all rivers shuttle and i'm sure she could make all your resupply points happen. If you're looking for a float partner on this Salmon/Snake Grand adventure let me know, I'd be interested.
