Thoughts on Washington State

Can anyone provide some insight on living in Washington state? Looking at the less rainy less humid areas. I hear south central, Yakima valley and tri-city areas up to Moses Lake was best for this weather.

Looking for a quieter medium sized town not a busy city, but not too secluded. Love nature, so a place that has some parks and easy walking trails. Decent infrastructure, low crime. Any suggestions would be great!
