I go in, just because it is boring out in the wilderness on my own. I go looking for better guns etc, but I don't need to. Making heals of whatever type only spawn in towns/cities requires me to enter the danger zone, after attrition in the wilderness has worn me down. At the moment, surviving is achieved by the "matches/hunting knife/hatchet/water bottle" combo indefinitely. I'd be in favour of getting rid of all heals from food and making it medicinal only.
