In 1791, the right to bear arms to defend against an over-reaching government wasn't theoretical. Today, it's hard to imagine physical weapons serving the same purpose. But it's easy to see how hacktivists might - especially if you broaden the opponents to include hate groups and rapacious multinationals.

I learned to dive in Belize, which is sort of like learning to drive in an Aston Martin. The reefs and refuges are some of the most dramatic in the world. But the real reason I went was to dive the Blue Hole, a 400 ft. sinkhole near Ambergris Caye. Google it, and you'll see why.
