A friend just sent me this link: http://nerdfitness.com/blog/2010/12/09/how-to-fly-35000-miles-visit-4-continents-9-countries-and-15-cities-for-418/
Pretty much the most insane example of travel hacking I've ever seen. Plus, it makes me really really antsy to get out there and do a massive, months-long trip of my own.
I haven't read nerdfitness before, but he's talking about a lot of the same principles as Life Nomadic.
I would say "I don't see how anyone can see this and not immediately drop what they're doing to do it," but, uh, I'm still at this job of mine for now. Only now I'm really champing at the bit...
