The Olympic Peninsula is a very rainy but quasi-remote region in western Washington. Albeit with strong reservations, it is one of the few retreat regions that I recommend in the western half of the state.
Statistics (for Forks):

Clallam County Median residential home price: $140,000.
Advantages: Mild climate with the moderating influence of the Pacific Ocean, Clallam County crops include hay oats, corn, apples, cherries, pears, plums, carrots, peas, and berries. Upwind from the Cascade Mountains (which are prone to rare but very violent volcanic eruptions/ash falls). Upwind from all of Washington’s anticipated nuclear targets.
Disadvantages: Extremely heavy rainfall except in some “rain shadow” towns like Sequim (spoken: “SKWIM”.) Proximity to the Seattle/Tacoma metropolitan region. One important proviso: Lots of folks in western Washington go fishing and hiking in the summer on the Olympic Peninsula, so they may immediately think of it as a place to bug out WTSHTF. So be prepared for a substantial influx of refugees in the event of any sort of rapid-onset TEOTWAWKI.
