With three rivers and many navigable creeks, Warren County enjoys a distinct advantage in profiting from tourism. Adding Cumberland Caverns and the Isha Institute into the mix, this community could be a powerful magnet for visitors from across the U.S. and many foreign countries, Tennessee Commissioner of Tourist Development Kevin Triplett said Thursday. “This county has done a great job” in promoting water recreation, mainly fishing and kayaking, Triplett told the weekly luncheon meeting of The Rotary Club of McMinnville.
