While the practical usefulness of snaring wildlife for food is debatable, after all, food is rarely a necessity in a short term survival situation and very few last longer than a couple or three days, I and others I know have successfully used simple snares to trap squirles and rabbits. Experience and hunting skills help a great deal in determining where best to set snares. The instructors at USAF SurvivaL School have told me that their experience with their students is about 10-15% sucess. That's one reasosn to set out lots of snares, if you want the best results and have limited experience. Just another data point.<br>
