I haven’t had the fortune to go to any rivers except the American Confluence River. It features a long (but not Mississippi long) stride of beautiful, clear water that goes quite fast, and along the gravely beaches there are a few shrubs of some kind. Whenever I go I always see another family or two playing in the water. My sister is afraid of heights, and whenever we go on the humongous bridge that goes over a ravine, she always grips her seat and holds her breath. It is always a blast to take a trip down there, and it’s only about an hour to an hour and half getting there.
