depends on forest, season, knowledge. there are some military veterans that have gone through ranger training living in woods central California into Oregon that have lived over winter a couple times, survived and some have gotten fat living off the land- crossbows for very quiet hunting along with shotgun for dangerous game- rabbits and squirrels for single meal and deer good for a month with preperation, Cammas and wild carrots, some greens and maybe a small garden for some of hermits in Ohio river valley. Fugitive from a mall terror bombing hid out in great smokies for about 3 years. pick forest with lots of edge growth, deer and small game, some flowing water and maybe close enough to town dump, might live awhile like guy in Wisconsin dodging police, had a bunker. spring /summer/fall in middle of country to northern area has had some of homeless with tents surviving fairly well until winter- just have source of water and be able to recognize edible growth, be a decent shot for small game, can live simply for long time until winter- then head south to Texas or Florida. Any are where indian tribes flourished is a potential living rough in tent area.
