And you get to see them! The guinea pigs on the bridge!
The Nagasaki Bio Park in Japan has a guinea pig bridge. As if that's not delightful enough, song-of-the-week guy Parry Gripp wrote a song about the guinea pigs and their bridge. (If, like myself, you liked Star Wars and pop punk in the late 90s, you'll also recognize Gripp as the frontman of the band Nerf Herder.)
This whole thing is really wonderful. If you are still reading this, stop and go watch that thing up there.
