I'm going to try to keep a diary on the trip. (This is most unusual for me to do so.) I'll keep good notes and let you know what we do, liked, didn't like so much etc. Which ship did you choose for your journey? We're on the Zenith. I hope we like it. In any case we will have a good time.
I just bought a video documentary about Pategonia. It's not very well made but it does have some interesting information and some beautiful camera shots. It looks like the Argentina side is pretty baron. The highlights there will be Buenos Aires, Montevideo and of course, the penguins. If you are interested, I can mail you the video to look at. As I said it is not womderful in quality.
