I will teach you how to backpack through continents, while spending as much money as you would paying rent in California. Last summer i spent 2 months in Europe, saw 13 countries and spent $2000 for the entire trip. This includes a $600 flight to Europe, $400 train pass. I spent 0$ on housing and i will tell you all about how i accomplished this and how you can too! My information is not limited to Europe, but universal. :)
