Take note of the Jan08 BOAT U.S. magazine article on our home waters. Article is about Knoxville to Nashville via the waters. The TN and Cumberland Rivers...some 850-1000 miles of river with supporting marinas about every 50 miles thanks to the BIG (Boating Infrastructure Grant) funds. The article stops in Nashville, but our family often boats on the more than 190 miles navigable miles upriver from Nashville to Celina, TN. You can go beyond Celina, but barge traffic channels are maintained up to Celina. Email if you missed the article. Some great "side trip" waters from the Great Loop.
