Time Travel

If you were capable of time-travel would you go forward or backwards?  When and where?

I, of course, would go back, since historical fiction seems to be my thing.  I always thought I would have liked to witness The Sermon on the Mount, because, I mean, it's Jesus!  But nowadays, since I'm working on a story set there, I'd like to spend a day in Ancient Caria (modern-day Turkey).  That would be mind-blowing.

I suppose I would most like to have the ability to go back to the places I am writing about, which would include such times and places as 18th century England, 19th century France, 4th century Alexandria (whoa), and early 20th century Russia.  I would have quite a time-traveler passport.
