You sure want to feed. The problem of a homeless person, if it be considered a problem, is not that he has no food, but that he has no permanent dwelling. Would you take a starving person and buy him a house? No. Neither should you assume a nomad is hungry.
As I've discussed on other threads, homelessness varies. Many, many persons in my state are technically homeless, but do not at all match the national stereotype. Many are successful seasonal loggers and other woodsmen, are only part-year residents of my state, and possess significant financial and other assets. It just makes no sense for them to maintain a permanent year-long dwelling. Some live out of cars, some camp in tents, some squat in abandoned or seasonal dwellings owned by others. Others lay their head at night on someone's couch. Few if any are independently wealthy, but none I've met were starving. Enough edible wild plants and fresh water sources abound in the Maine woods to support a great many persons. But no, in the event of apocalypse do not head here. That bridge over the Presumpscot would not be long for this world.
