A few years back my father and I were moose hunting. I shot a young bull and he dropped on the spot, right there on the quad trail. Pulled up, gutted him, loaded up, and away we went. Next day we are out to fill my father's tag. Late evening he sees a nice bull at the edge of a swamp, shoots and he charges about a 100 yards into the swamp and falls dead. By the time I get there, its too dark and we can't find the bugger. We figure he'll cool nicely in the cold late October swamp water and look in the morning. Next morning myself, my father, and my grandfather go out to retrieve him. Spend and hour looking for him, finally spot him. Guess who the youngest and mostly likely to wade into the swamp is? It's definitely not the grandfather. Strip my pants, boots, and socks off and away I go into the swamp up to my belly button to wrap a rope and ATV winch lines to pull this bugger out. By now this moose is stiff enough that he provides a hell of a workout that at least warmed me up while we gutted him. But that was the easy part. We spent the next 7 hours, cutting trees/trails, flat tire on the quad trailer hauling this guy out, broke through an old ATV bridge, and having to recover the quad and trailer/moose with two winches, and 3 guys pulling on a block and tackle by hand until our eyes were bugging out. By the time we got out of there we were exhausted and sore. Meat was great though, no spoilage. Was it worth it? Yup. But I really prefer shooting them there on the trail...
Moral of the story? I wouldn't hesitate to shoot one on the edge of the swamp again. Was it a lot of work? Yes, but with some proper/improvised tools, the right company, a lot of sweat and swearing, we have a fun story to tell that 3 generations got to share together. Good on you OP for following through and I bet you'll never forget the experience.
