so I would like to start saving up for a trip I want to do, but I don't know exactly where yet. This is where you macrumors come in, where would be the best place to backpack across and want to gain lots of knowledge and experience the rest of the world. I was thinking south america or europe. Also I would like to know how much I would need to save up for a trip like this. I would like to go for atleast 3 weeks.
