I was going to go where Thomas went - WIND. Ha!
It is hot in the summer and cold in the winter. You are a hop, skip and a jump from real mountains.
You are right off a main freeway, so getting to most anywhere distant, be it Seattle or Spokane, is a breeze.
The area is a mix. A lot of desert like land with, for lack of a better term, an oasis here and there. A friend is north of town and surrounded by Hawthorn trees. A small year round creek ambles through his dirt, and can roar in the summer.
In addition to prepping against both cold and hot, consideration
should be given to fires, which, as the intermittent news indicates, can happen any time.
My friend has
electric heat, but heats, exclusively, with
wood.
He raises goats. He has a pistol because, occasionally, big kitties want one, or the
chickens.
You are not far from orchard country, about 45 minutes east, via freeway, where I live, surrounded by thousands of acres of apples, cherries, fields of onions, potatoes, peas, corn, buckwheat. . .
ALL that aside, even south of and close to Spokane has some interesting country. Sparse pine trees and many bodies of
water, big and small.
I grew up in the Okanogan area (actually, Brewster and Ephrata). That is some beautiful country. More beautify if you can get away from the towns and cities.
I loved the Methow valley, but Microsoft and Amazon types have priced much of it out of reach of people prone to a conservative (tame) life style.
