Leaving in one week

I am leaving for Cambridge in one week, and no part of me really feels like it is happening. I will fly out of Philadelphia on the night of the 28th, arrive in London on the morning of the 29th, and take an hour or so long train to Cambridge. From there I go to the University, get my key, and go to my new home at 102 Barton Road.
I hardly know where to start to get ready. It would be nice if all of my trip logistics were actually worked out by now, but they are not. I still don't have my visa and I am still waiting for two loans to be confirmed. But, ready or not, here I goooooo!
