Re: Home state of Oregon??
Yes, all that's in California is the HQ. Most of its US presence is here in Oregon, which is why it's big news in The Oregonian (front page of Saturday's paper, IIRC).
There are pieces of it in Beaverton, Aloha, and Hillsboro-- all suburbs of Portland, so from a sufficient distance (like El Reg Central), "Portland" is a reasonable enough approximation.
Also, those with allergies may be happy to know that development has displaced all the grass seed farms in between Hillsboro and Portland by now.
