Those of you who have been reading this blog know I am a great fan of Doctor Who, the British TV series that is now 50 years old give or take weeks/months -- I don't have the details, but it first came out in 1963. Some of my fellow About.com Guides and I have been discussing where we would like to go in the TARDIS, a device that the first Doctor's granddaughter, Susan, during her Aztec adventure, says she named. TARDIS stands for Time and Relative Dimension in Space. In other words, it's a time machine that can travel in space. Please post in the comments where you would take the TARDIS if given the opportunity. If you like, you may specify the Doctor accompanying you.

I would go back to the moment that Caesar took over Legio X for the Gallic wars and become one of his legates.

The Library of Alexandria, before any burnings. I might not be able to read a lot of what was in there, but with a digital camera and some university contacts, I might be able to get translations.
