Timbers Army's Beer Buses?

This intrigues me a great deal:
The Timbers Army has filled its section in the Northeast corner of Qwest Field, and the flags haven't stopped waving since the raucous group hopped off its 10 buses (each nicknamed after different Oregon breweries for the journey) and noisily made its way into the stadium.
The Army went north to do battle against evil Sounders (and their apparently wildly insecure fans) last night, lifting them to a 1-1 tie. But I'm interested in those buse--anyone know the breweries they were named for?
