While those who have visited World's End in the past can find it more easily the more familiar they are with it, others tend to wind up in World's End by accident. A distraction en route to a destination, a blinding storm, a sudden loss of control, an ambling hike through nature, or a long road to nowhere – all are some ways in which travelers have found themselves in World's End.
Those trying to find their way back, of course, may have greater or lesser difficulties in doing so depending on what brought them here. Those whose worlds have ended, of course, may find themselves in World's End without a place to go to - but for most everyone else, a stop at the local Gas and Go is likely to give them the directions they need to return to their home dimension, if not necessarily to the same place they left it from. Occasional references to World's End, Missouri on some landmarks suggest that this town may originally have been an actual location located in Missouri in the United States of America on Earth, though it does not appear on maps (including those sold at the Gas and Go.) According to its post office, it does have a zip code (64246), and mail does somehow find its way to there.
Of course, one can always throw caution to the winds and attempt to walk, drive, or fly away without a particular destination in mind – leaving the borders of World's End always takes you somewhere related to what you might be thinking at the time. The transition between worlds can be sharp and jarring, or practically unnoticeable, depending on one's perceptions and conveyance. For safety's sakes, the World's End Tourism Board advises that people entering or leaving the extreme borders of World's End do so with as little sensory guidance as possible – eyes closed, navigational equipment disabled, et cetera, for a period of up to ten seconds to ensure a smooth transition to a neutrally equal location.
