plus the Spring just below the Missouri/Arkansas border for a fun little float. No camping on the Spring other than at outfitters' campgrounds, but the fishing is great; trout, smallmouth, walleye, etc. South Fork of the Spring is a quiet, often overlooked float with great fishing for smallmouth, largemouth and spotted bass. Regarding the Buffalo, with a couple of exceptions the lower reach doesn't have any whitewater to speak of, but it does have great gravel bars for camping and outstanding smallmouth fishing and is runnable when the rest of the river isn't. It's a bit of a hike from Van Buren but well worth it for float camping. The King's river is also nice if you catch it right. As for where to get a boat, I highly recommend Ozark Mountain Trading Company. Super nice guys. They're based in Garfield, Arkansas but just opened a store in Ozark, Missouri outside of Springfield. They will fix you up with whatever you need and will be a pleasure to trade with.
