For the students who have applied for this trip -- let me say this: you made the right choice. We're going to have a blast, and you're going to learn some pretty cool things along the way.
Check this blog out -- it's a year old but it has some interesting things to say about London. I'll be updating this throughout the rest of this semester, straight through our trip.

The first thing I do when we get to Scotland? Delve into some fried Mars Bars, and Irn-Bru; the official drink and snack of the Scottish.
