Walkabout - Australian Aborigine term by which young boys, having learned survival skills from their parents, head into the Outback (wilderness areas) of Australia for weeks or months on solitary journeys, live off the land, be spiritually enlightened, and begin the process to go from boyhood to manhood. Vision Quest (translated into English) is the Native American term referring to a similar journey. On a limited scale, due to limitations of modern world, these personal journeys continue today for these cultures.
We 'western civilizationers' have changed things up as we do not make that kind of time for turning kids into adults. Sending children out for these kinds of extended periods alone has never been part of our western culture. We do condensed versions - sending kids on solo overnights, maybe a backpacking trip for several days to weeks and usually in groups, or perhaps sending them to summer camp where the hope is, kids will get similar revelations, via experiences and interactions, about growing up in the world.
