I personally like the Amtrak century in California. There were some other ones in the San Luis Obispo area (like the Lighthouse Century) that were really great! I don't know how many are still in existence and I don't know of any great ones in WA yet but if you want me to go through my stuff, PM me and let me know! I can also provide websites, if you want.

There was a really great one in Paso Robles (Calif) but I have to check to make sure it's still around
