Great to see the update. This has the potential of becoming an annual event for you and your kids. Lots of great rivers across the country. From my experience nothing builds a stronger connection with your kids than quality time spent in the outdoors.
Perhaps if more parents took their kids camping and boating instead to Disney and the mall we would have a better society.
Take lots of pictures and if so inclined post up the one with the biggest smiles. The only thing I enjoy more than a good day on the river is seeing that "aha" moment on the face of someone on the river for the first time. That is magic pure and simple.
