I found a pseudoscorpion.

Ray Harryhausen giant clawed land crab beast.

This monster was in my garage stalking a scrap of newspaper.  I had no idea what it was so I trapped it, took pictures, and ran to wikipedia.  Turns out it's a pseudoscorpion, and pseudoscorpions live in Oregon, just people don't usually see them.

Not really giant at all.  At least it's not a tick.
