I myself like to ruff it out in the wild right from the start building up my skills, not even stepping into a town.
Its a great way to play.
My only problem is finding easy drinking water, I usually live off apple juice as much as a can, but water should not be that hard to come by right?
Rain water should suffice, but the problem is that to make a funnel you need plastic bottles, and that means usually going into suburbia.
So here is my idea: Litter!
Its everywhere in irl so its not a stretch for it to be in cataclysm.
Find it on the side of roads, by highways, hell even in town(litter was the least of there problems when the shit hit the fan).
Sure most of it would be useless crap like empty chip bags and soda cans, but there would also be plastic bottles mixed in there too!.
Perfect way for you outdoors men to get your hands on some of that sweet life giving liquid!
