knee problem

I have a sore knee from my bike trip, which has become sort of a re-occuring theme in my long distance cycling career. I adjusted the saddle height during the second day, so that may have something to do with it. I'm just a little frustrated because it seems like hundreds of other people are able to go on trips that are a month or longer, without any significant problems.

Well, at least my bike didn't fall over and slice my leg open with the chainring. It would have sucked to have to get a ride to a hospital and have it stitched up and not get back to camp until 2am.
