This company does not work you out of hubs or terminals. What areas they hire out of is based on freight going into and out of that area. Your best bet is to give them a call and ask.
They have a drop yard in Kent WA off HWY 167 It is in the back of the SEA/TAC Box company.
I live in WA and I worked for then for almost 7 years.
They are a east coast company and have very few facility's on west coast. Better to find a company that has a terminal closer to home unless you just need to train.
