There have been a BUNCH of nice buses in WA lately but it has dried up a bit.
Puyalip has a bunch of gas powered conventionals but not much else going on right now.
Have patience and keep watching the auction sites. I bought mine via GovDeals and picked it up in Salem OR. Keep your eyes on OR auctions as well.
We have also seen a handful of members buses offered for sale this summer. A few of those have been in Western WA. Keep an eye on the classifieds here.
