The Sixth Law: set out without knowing where you will sleep that night.
In keeping with the somewhat carefree nature of my choice of seven laws of adventure- the sixth is the most important law of all and a direct steal from Reinhold Messner who considered, after a lifetime of arguably unparalled adventure that it took him thirty years to realise the essence of adventure was exchanging the familiar hearth for a sleeping place that was unknown at the day's start. This is why hitching can be the ultimate adventure and an ascent of Everest not be. On Everest every camp site- if things go well- is preprogrammed. With a hitching trip - nothing is programmed. On well organised expeditions the adventure starts when there is a cock-up or accident. A good expedition is fun alright but it may lack...adventure.
To set off, knapsack on back, no money in the pocket and no knowledge of where you will kip that night- but a goal of sorts in mind- now that is an adventure!
Of course, the remoter the spot, the more 'unknown' the sleeping site will be. I have found that there is nothing quite like being super remote from the rest of humanity. Sleeping rough on the edge of civilisation has its own feral charm and edginess, but choosing a campsite in a place where the next human is 200km away, that is special indeed.
