I have been watching some of the real survival shows on TV, Survivorman, etc. They have shown the use of snares for hunting small game. However, can a person use a snare to catch and kill a large animal like a deer in a SHTF incident? Would New Zealand fence wire, rope, cable, grape vines, or other items be used to make the snare? What is used for the lock? Just trying to start a discussion on this matter and not get into a flaming debate about killing, meat eating, vegetarian, etc.
