Boston in one week!

I leave in one week today to attend the iGEM jamboree at MIT in Boston. Totally uberexcited about it.
We spend three days at the Jamboree, and one extra day to see Boston. I hope to get a tour of the Medical School at MIT, or maybe get a chance to meet Craig Mello (who I've had the pleasure of seeing lecture before) or H. Robert Horvitz! We're also going to visit Harvard, but from what I hear, you cant get into any of the buildings except the bookstore if you're not a student. The guards make very sure of that.

I admit, though, that I'm not very familiar with Boston, so if anyone out there knows of things to see in the city let me know!
