How to Travel Around the World for $418

I happened to come across this guy - Steve Kamb - who decided he wanted to travel the world for as little money as possible. He downloaded an e-book, read it, and comes up with a travel plan: 35,000 miles, visiting four continents, nine countries and 15 cities for just USD$418.

• Sydney, Australia – Feb 15-20
• Auckland, New Zealand – Feb 20 – Mar 20
• Brisbane, Australia – Mar 20 – Apr 9
• Alice Springs, Australia – Apr 9 – 12
• Perth, Australia – Apr 12 – 14
• Singapore, Malaysia – Apr 14 – 16
