Look at what this couple is doing.
They are traveling in their completely refurbished off-grid RV that is towed by a truck running off waste vegetable oil. How cool is that? And they document their journey on their blog and the money they spend, which is next to nothing when compared to owning a house and a car and whatnot.
This is what me and @roycedaniel want to do once we're kid-free in 6 years. So I can write my books and he can ride his motorcycles and we can together travel across US. Wouldn't that be swell.
