I find it very curious that expense is the first thing that comes to mind for a lot of people when they hear about trips like this. I understand it is expensive, but so are a lot of things that don't trigger this question. Is it just because it requires eliminating the safety of a regular income? Replacing my roof cost as much as a year of traveling, but nobody ever asked me how I could possibly afford to replace my roof.
