Government counter-terrorism officials gamed out a very likely terrorist scenario in a Northern California drill this week: That of marijuana growers setting off bombs, taking hostages, and laying siege to a strategically critical dam. We are so prepared for this!

Did you know the world's largest beaver dam can be seen from space, if by "space," you mean, "Google Maps"? It is in Alberta, Canada; it is a half-mile long; and it probably took two decades to build.
