Connie,
Lots of us have walked that stretch. Its not a bad stretch at all. The whole trail from Boonville to Machens is essentialy flat as a board. You might run into a few rises crossing roads or levees, but nothing daunting. Take water and a snack and take a break or two and enjoy the scenery. Are the people going on the walk used to walking at least that far? Decent shoes are a must, and have a good time.
