a couple of years ago, before i could hunt, i helped a friend look for a deer and we followed her into some of the thickest swamp and there was a blood trail for at least 1/2 mile. we finally found a spot where she went around in circles, but we still couldn' t find her. we looked everywhere, even under the roots of windfalls, but to no prevail, and to this day that hunter hasn' t gotten a deer, but we have faith that someday he' ll get one.
