I' ve shot a lot of evening deer. Yep, own lots of flash lights. Recovered a lot of deer. Some at night, some the next morning. One, the coyotes got. In a perfect world, every shot would be at 15 yards, a double lunger with a complete pass through. The critter would go about 20 steps and crash.[:-] In reality, folks get excited, critters move or jump the string, a branch or whatnot deflects your arrow, or whatever and you have to trail them. Sometimes pushing an animal that taken a marginal hit will only push him into the next zip code. Let him relax and lay up, and you' ll find him the next morning.
