Justin, I went to Belize last February. You can check out my pictures here
csciambi's photos and albums on webshots , to give you something to look forward to.
You are doing a rotation in Belize, what kind of rotation? The only rotation I am familiar with is that of grad students rotating in different labs to see which one they might want to do their research in.
Well, 2010 will give you a lot of time to prepare. I look forward to hearing more about the reason for you trip (maybe I will find that info elsewhere on this site), and what you will be doing while you are there.
