We were thinking about this with our last bear. We made a harness with 5 seperate ropes and had 5 guys pull from the front. We had the bear on a piece of plastic so it could slide on the snow. We had our 6th man walking with the bear and trying to keep it from rolling off the plastic. Once we got it out of the swamp, we had a couple hundred yards to go. We had a guy with a small saw walk in front of the ATV and cut down saplings so we could fit it back. The last couple hundred yards were through overgrown clear cut so it was tight.
