Doing a NF Flathead trip and looking for shuttle recommendations. Flow is looking to be around 4' which I have been told is still moving at a nice clip. Would the border to Blankenship be too much for a three day trip? I figure 20mi/day isn't too bad if the current is moving along nicely. I am also considering taking out before Blankenship if needed. Any thoughts on distance and shuttle company shout outs would be appreciated. Cheers.
