Last days in Bonn

Today and tomorrow are the official last days in Bonn. I'm so sad that it has gone by so fast. Today was an excursion on the Rhine though which was really fun! We saw the oldest non conquered castle in Germany. It had some of the most interesting facts about how it was strategically located and how the cannons were placed. It was ruled by five different groups of people since the 11 century (or something like that). One of the most interesting facts was the way they situated the chapel in the castle. It was lower then the rest of the castle and had very few points of entry and those points being very small so if a knight was trying to rush into the room the defenders could defend it a lot better because the knight would get stuck. Other then that tomorrow is my last final Math 308 (please kill me) and reviews for everyone and a picnic I believe. May 2nd don't forget now!
