Sorry to hear about the wounded deer...I haven't met a hunter yet that likes to lose game, even when they've done everything they can.
Laura killed two does on the second morning of gun season down here, and I thought she missed both. No blood trail in the food plot. We got 50 feet inside the woods, and it looked like someone spattered red paint all over. It would be nice to try and track in snow!!!! We were trailing in wet leaves and pine straw... "I got the trail...oh, no...wait...just a leaf..."
Your post reminds me of when I was up in Wausau visiting my folks over the holidays several years ago. We were up around Minocqua and further north, hitting shops and visiting, and stopped on the way back just outside Wausau at a restaurant/bar/tavern to get a pizza. There was a truck in the parking lot that literally had deer stacked in the bed like cordwood. Old, beat up Ford, I think, squatted down, no tailgate, frozen dead deer just stacked in layers in the bed. Something like 15 or more, if I remember correctly...
