Wow, I post this thread:
This note is for you Steve.
and the next thing I see is "traveling the world".
Cooooool!
I'm sure it's a great goal.
(By the way, I don't see why you cannot take your children with you, at least in two years or so... just ask your local travel agency. I actually think it is a bit "american" to be too secure when it comes to this. There is always someone, even in China etc, who speaks English. And if so you'll get around no matter what.
