Neal I've held off to now. I hunt the same places in the same weather as you. I wear a waxed filson ball cap from the Washington Brant Festival, when it starts rainin I occasionally put on a goretex sou'wester (but they leak), been thinking of a Helly Hansen rubber sou'wester, but when it really rains I just put up my neoprene jacket hood.
I tell people that Alaska natives have 43 different words to describe the amount, intensity and duration of snow. Well real northwesterns have 43 different words to describe the amount, intensity and duration of rain. Ever heard of sun breaks? Can you differentiate between fog, mist, sprinkles, drizzle, light rain, rain, downpours, gully washers and a horse and a flat rock? Sometimes you just need a full body neoprene suit.
