Wait, wait, wait. If the man needs 2 lb of food daily to chase gunkid, doen't gunkid need at least 2 lb of food also (and probabily more as he as to drag his assault-wheelbarrow.)
Now gunkid will have to cover his tracks (energy wasteing exersize), keep away at all times wondering if the searcher is closing in (another energy wasteing exersize), keep looking behind himself, in front, to the sides. I think gunkid will need MORE than 2lb of food daily, not to mention at least 4 to 6 quarts of water. Where will gunkid get that water and make sure it's safe to drink? How will gunkid know where he is, or what the land is like around him, or if he is heading into a swamp?
The answer..... gunkid will croke in one day. Bigtime.
