Oui mais là ce n'est pas une question de prix ou de gratuité, on voulait vraiment dormir "in the middle of nowhere" et surtout au milieu de personne.
J'ai envoyé un mail à l'organisme sité plus haut, je vous colle la réponse elle pourrait servir plus tard :
Thank you for your question. Without a better idea of where you plan to do this, it is a difficult question to answer.
The answer will depend on where and under what circumstance you are camping
. Generally the answer is yes, this is allowable. However… along certain large or busy roadways and highways this would not be allowed, but along other quiet and remote roads it will be allowed. Inside certain cities and towns it would not be allowable; other cities and towns may have places for this. Depending upon who owns the property you park on will also determine if you may or may not.
Certain special places will not allow this… such as most National Parks and many small parks or municipal roadside picnic areas. On the other hand, most –but not all - lands managed by the Bureau of Land Management or the US Forest Service will allow this.
Another thing to consider is your safety. There are certain remote areas in southern Arizona
where illegal smuggling related activity is occurring and these would not be places to recommend for camping
. However, most of the state is perfectly suited for this activity and you will have a wonderful time doing it.
comme ça a l'air d'etre un "oui" avc pleins de petites **** si on est toujours motivés on demandera au visitor center et sinon ben on ira trouver un camping
