Preparing for take off - Any Advice?

Wow, summer is moving along at a blistering pace! One of the reason that posts have slowed a bit is not only that our Summer Institute is taking a lot of my time, but the fact that I am preparing to leave in a few weeks for a short stint at Oxford University to finish up my doctoral studies. I have spent most of my spare time reading in preparation for my coursework and have had little time to ponder the sights I may have the opportunity to take in while there.

So I figured I would ask the readers of this blog: Any suggestions on "must visit" places in either London or Oxford? I thinking outside of the standard sights (Big Ben, Buckingham, etc.) that most people always visit. I always enjoy the sites that are a bit off the beaten path....any ideas? Feel free to leave comments or e-mail me.
