Hi Greg, Ashley, & all,
Google Arkansas State parks, Bull Shoals, and Nimrod Lakes in very north Arkansas. Also Mount Magazine (The highest point in the state and has a new lodge) and Cove Lake (nearby) in west central AR.
In the exact middle of AR is Little Rock. There are no waterfalls, right on the edge of AR mountians vs Mississippi delta (SW to NE diagonal).
Still, lots to do. Just don't come here without letting me know you are coming.
Would be delighted to meet you.
