Yea - cool site. I did some reading there today and came to the conclusion that we are WIMPS!!
Those guys are flying all over the world, and we just need to find a new campground to park our beasts. Think of the downsizing of "stuff" THEY had to do! They are rockin the nomad scene with just a suitcase!
Lots more there to read. I may even be interested in that guy's e-book on the subject. Sounds interesting.
