RE:Hide the women and children...
Cow is awesome in October. I fished in tight along the run below the ramp. Needed a raft to get to the island, but two guys who did it got 5 in an afternoon. We ended up landing 9 fish over the 3.5 days, more were hooked.
Kalama is out of this world in October, dry lines in skinny water and fish hiding behind boulders willing to explode.
Also had some great days on the Upper East Fk Lewis in October, I'll dig up some good pics from there I have w/ blushing steelhead about to swim free.
