Thanks for saying that John, I have never fished any of the western rivers but have float the Chattahoochee River numerous times. Fishing the entire time, I have spent 8 hours or more several times on 2 to 5 miles of river. Twenty miles seemed long to me and 35 miles sounded like constant rowing. If something go wrong there would be a long way between point where help would be available. I'm guessing cell phones are pretty much useless along many of the rivers. I would rather arrive at my campsite with time to spare than float down an unknow river in the dark. Mark is smart to ask ahead rather than having harrowing tales to tell later.
