OK. I'm on a 5 minute break. First of all: I'm not here for the olympics, its crowded enough as it is.
I would say that the hardest part would have to be that no one (or at least most of the people) don't speak English, so communicating is somewhat of a challenge. I'm here doing some study to help advance my speaking, as well as just plain exploring.
I don't have much time to talk at the moment, but I'll 'try' to get back to you later.
EDIT: Oh yeah, and plenty of photos.
