There were 6 of us - me, my wife, our boys (22, 17 and 16), and our 10 year old girl. We rafted down the Pigeon River, upper (whitewater). It was terrific - not too intense (levels 3 and 4) but fast enough in spots to feel the thrill of whitewater rafting. Our guide Jeremy was great, guided us through the rapids flawlessly, very pleasant, knows the river well. Ask for him.
We really enjoyed the journey, great way to spend an afternoon.
