I just happened across your site (via StumbledUpon), and I can't tell you have envious I am of your trip. Many of us wannabe nomads have thought about doing what you guys are doing but don't have the balls to toss our stable lives aside and start really living. I love the way you're doing too- great minimalistic tools/gadgets and keeping a website as a record of your travels and experiences.
I'm sure I'll keep checking in on the site periodically. Enjoy yourselves and have a kickass time... for all of us who wish we were there with you!
