I was born in Tacoma, lived 50 years in the Puget Sound area...what you say is true, most blacks moved there because of Fort Lewis and McChord...it’s a friendly area, no latent bigotry of any kind. But deeply socialist, and the blacks either self-selected or were herded by real estate into certain areas within cities. It is now a ultra-green area, development of any kind is discouraged...just look at the awful roads...
Well....the awful roads come from zero state income tax, and the public has to make it off property and a sales tax. After being stationed there in 1980....I got smart and ID’ed the state as my home state, and for the remainder of my career....never paid any state income tax.
I admit....when you drive around the regions outside of Seattle and Tacoma....it just gets worse. When you get east of Mount Rainer...I wouldn’t be driving on any county or state road more than 45-mph (at least by what I observed in 1980).
