Replying to Studying Abroad in London

Hello everybody reporting live from some where,

Today I start the adventure of a life time, I leave for my semester in London.  And it hasn't hit me yet, I'm stoked to say the least but a bit sad that I won't see a lot of my friends for potentially a very long time (I'm a senior and a lot of my friends will be graduating after the fall semester). 

So is anyone else going abroad? and if so where? Also to those who have gone abroad before where should I go? Where was lame? And any tips that you picked up along the way that helped? Thanks everyone and I'll post some pics along the way and for sure once I get back.
