Japanese people know everything they need to know about Oregon.

As I left the ticket gate at the train station on my way to work this morning, I accidentally kicked something on the ground that make a little "clink" sound. Looking down to make sure I hadn't dropped anything, I thought I saw a bottle cap. Upon closer inspection, it turned out to be something far more spectacular: a little pin-back button. But this isn't any ordinary button; it is a concisely-worded treasure map. If you know what I mean.
