My fondest memory of your state was a vacation we had when our kids were pretty young. We stayed in my Uncle's cabin on Vashon Island, hiked all around Ranier, went to the Olympic peninsula...ten glorious days in the nineties, no rain, all sun.
Pretty rare for your neck of the woods I'm told.
We get good stretches in the summer, say August and into September....That's on the West side of the State. Eastern WA. is a lot dryer, also colder in winter.....
......Westy......
