Thanks to

The Cannon is
a continent away. :(
I would also like to join Pino in congratulating Caltech security. Well done, guys. Seriously. Chase us around the tunnels and eject us from them whenever you can, but don't worry at all about a 100 year-old, non-RFable cannon being moved. Geez.
How embarrassing.
