I am becoming more concerned about the rip rap, each year. Like Jayhad mentioned, some great stonefly action occurs along these stretches, especially in the NW. It is just that, as I get older, each rare fall I take seems to hurt a little more. I am seriously worried I will inevitably break something besides reel or rod (already done that) some day. Rocks that look stable can roll out from under your feet when you step on them. Rip rap can be a serious menace, a dilemna with no apparent solution, given just how much of it there really is lining the banks of the river.
