I want to backpack pretty much across the world in the duration of 9 months to a year. I would start in South america making my way up towards the Caribbean and maybe venture in to the USA for a while. From there travel over to Europe and the Middle Est ending in asia before heading back home to AUS. Do you think this is achievable??? I no its a huge feet and will take time for me to save the money and do the research but any comments from people with backpacking experience would be appreciated.
