I highly recommend going on a tour of the historic Hanford B Reactor, north of Tri-Cities, on your way to Seattle.
Google "Hanford tours" for the government website where you have to sign up, as the tours are very popular. But you will visit a place like nothing you have ever seen.
Free, too. Can't beat that!
I'd go along with that, for sure. My dad came from Denver to the Tri-Cities in 1944 and his first stop was the "B" Reactor. Hanford was the place where the plutonium was made that ended WW II. Fantastic tour!!
