For many its a bit of a pipe dream. Many who want to leave it all behind and wander for weeks or months don't have much. of course the reality is it costs money to travel evn by especially by bike. 30 days of food and gear to cross the US vs a $500 plane ticket but its about the journey and the wander. Those who actually tour have the dedication and fortitude to hold real jobs, go for a week or two a year or are so well off or young they can pick up and go for longer. As much as its a test touring is about freedom and adventure mixed with nature and to some extent living off the land or at least living on the road.
