Thanks so much!
I'm a backpacker, so I'm used to packing light. We will be on 2 Southforks by Bucks bags, and one Classic Accessories Wilderness 12 (I think). Most of all the equipment is my backpacking stuff, so I'm thinking that will help. Although the smaller size of the "cargo" area may increase individual boat weight.
I hope I included the image right. The green boat is what we are taking 2 of, and we are taking the newer version of the red one (really only the color changed)
I was thinking that parts of the West fork of the Bitterroot may be somewhat similar to the Smith.
Canoe's aren't an option as I already own these boats. (I fish the Bitterroot often)
Also as you can tell I do have room for others, if the water holds. Everyone else is bailing out due to water levels. It's a family float, with fishing.
