Looking for more traveling tips?
I been giving it a lot of thought, and its decided, i'm going to head down to Mexico by foot and keep heading south , hopefully i can make it all the way to Argentina or Brazil at least.. I'm taking very little money with me, no car, all i have is a backpack with clothes, sleeping bag, and about 300 dollars, and just hitchhike, or taking the bus south, its long been my dream to travel, Any tips you guys can give me, more survival essentials maybe?

Before I left home, I be seeking and reading every word of blogs from people who are also traveling in the same area. I would think that your safety is not at all assured. Not only are there plenty of people who'd rob you for your shoes, not to mention your three hundred bucks, but have you ever walked the desert alone? Try it in southern Arizona or New Mexico before taking off. It can be grueling, the task of carrying the water you need fully daunting even if you're quite fit. I know a woman (online only) whose family is bicycling from Alaska to Argentina. I believe they're in Mexico now. Read their blog at http://familyonbikes.org/blog/
