Playing at Patton Square City Park in Portland, OR this afternoon, some kids found this really cool caterpillar. Posting a photo on facebook led to many suggestions, including the Polyphemus Moth, Luna Moth, and Tomato worm. Regardless of what he was, or what he will be, he was really, really cool to watch. What do you think?

Polyphemus Moth Caterpillar

Dear ALW,
Your first choice was correct.  This is the caterpillar of a Polyphemus Moth.  The Luna Moth is not found that far west, and the Tomato Hornworm does not feed on oak.
