If you are ever headed up Hwy 69 toward Sudbury, you should check out the French River Visitors' Center. Among their displays is a recreation of the bottom of a rapids filled with artifacts drawn from the history of human traffic down the river, from the first peoples until today. You walk over the rapid on a glass floor that gives you a clear view of the river bottom below.
I'd love to see what you'd find at the bottom of some of the rapids on the Petawawa. On one little drop below Radiant (maybe the swift just above Francis Lake) you might find a shiny bright reflector oven that John left there years ago; or better yet, I imagine the remnants left behind in the pool below Crooked Chute could tell stories that would make your hair stand on end. . . might even include a few bones . . . could be the stuff for some good fireside tales this summer.
