Southern Hemisphere

I am getting ready to fly to Buenos Aires on Thursday. I thought it might be a good idea to get travel insurance for this trip because I will be spending most of my time in the mountains in the tree dimensional world of rock climbing. This is my first time buying travel insurance and after buying it the website prompted me to start my very own travel journal (blog??) I am somewhat unfamiliar with the blog world and i don't even know if anyone will read this (or how).
