I considered taking the Roamer to the raft up but after discussion with others, I decided that it would be more valuable at A Dock as a staging spot. The raft up is only a 5 minute boat ride in a fast Donzi.
Jim, you can ride up to a park and the base of Chickamauga Dam. It is around 5 - 6 miles. It is not as pretty as the Gorge but makes a nice run. I do it on occasion. Any further and you will have to lock up.
