Why is it whenever I visit London my boogers turn black?

Just got back from a day at Windsor Castle. It was just what I needed: a nice day out to remind me why I am here. I have been so caught up in school and what's been going on in the house that it was starting to get me down. After today, I am energized. The town of Windsor is great and the castle is just amazing, especially because it is still used on a regular basis. Hard to imagine that something THAT old is still actively used by the Queen today. The rooms were great, all very ornately decorated - very gold.

I guess the only thing I have to compare it with is the Biltmore Estate. (My sister and I toured the White House when I was 8, but I can't remember anything about it...) The tour was similar, view the rooms/view the grounds, but there's something to be said for a piece of architecture built in 1080 that the Biltmore can not be compared with... And the artwork, each room was covered in beautiful paintings. The most impressive room was St. George's Hall, an enormous hall with a vaulted ceiling that is covered with coat-of-arms for all of the members of the Order of the Garter. This is where the Queen holds State Banquets.
