For your goal of traveling to all countries:
There are travelers' clubs--one is called something like the Travelers' Century Club (for people who have visited more than 100 countries)
What is the purpose of joining these clubs? I have just completed my 109th country (Actual countries not their inflated list). Im considering joining their association, but cant figure out what you get for the $150 annual fee other than a regular magazine subscription. Does anyone know if the benefits are worth joining?
