>>2629085In the off chance this is real and you're not some 13yo retard I will help you.
I was "homeless" for around 2 weeks around Paris (not even broke, just got kicked out of my dorm and was waiting for another rent contract to start so decided to give it a try instead of paying the airbnb jew), and I slept in the woods near Rambouillet (forêt domainiale). plenty of places there, no one ever bothered me. I even commuted to the train to go to university and work 4 days a week. A sleeping bag is not enough, you're losing most of your heat through the ground. At this time of the year if you stay dry your clothes are enough to keep you warm enough during the night if you are insulated. Tarp + ground mattress is way to go.
Stay out of built up areas, in the 92, 91 and 77 all towns have weird homeless guys who might fuck with you and steal your shit, even the nicer ones you wouldn't expect because you don't see them all day. They mostly don't harm you they can still bother you and interrupt your rest and be weird/unstable so I suggest staying away.
I also tried this in the fontainebleau forest and there got bothered once by a forest guard and I told him I lived near by and he just told me to fuck off and go home but I didn't get a fine or anything. At the time I would go to uni where I had a locker in the sports club where I kept my computer and clean clothes so I would clean up, shower, and charge my phone there. I would also get food and water from the city by literally buying it. If you don't have any money or access to these things you also need to plan for this. Instead of breaking into people's homes like a gypsy you can bust open the dumpsters of large supermarkets just after closing time, when the employees throw out things that expire soon. Especially in the suburbs they are really full and usually easy to access on parking lots etc. In the summer only things like bread and vegetables can be salvaged, but in the winter meat and dairy is game.
