I was floating a section of the upper Klickitat this fall. I had just beached my pontoon and was walking out and down into a run while I made some preliminary rolls to get some line out. I must have overpowered the anchor with a forward stroke on one roll, because the fly snapped into the boat behind me with a loud metallic twang. The fly was embedded in the bow of one float. I wiggled the fly but that just made the air hiss out more. I had a couple more miles to go. I just clipped off the fly and left it in the float. I finished off the day with hardly any air out of that side.
