Just in case you decide to try any rescues along the way, here's a list from Whittier to Eugene in order. If you have unlimited long distance good luck with this, I'd try maybe every other one at first and see how far they can relay. Most of these also have e-mail adresses listed on petfinder.com, just look up shelters by state.
Tell them about your case and see if they know anybody who would be willing. You might just need somebody to connect between one or two places along the way.
