Thanks for all the info! If I weren't in the process of buying a house, I'd definately be looking a 17 - 20ft alum boat. But that may have to wait until next year. For now, I just don't want to miss a shot at the Lake Wa fishery. I've never done it, and may never get the chance again...
I'll look into using a downrigger or deep six.
Entiat would be an ideal spot for me. It would be easy to get a few hours of fishing in before work. That way I won't have to worry about catching the full blown sockeye flu...
