Md... Sweet bull and wolf! I missed a big blacky this fall, I hit right under his chest... Still sad over that one.
Did you split the hind quarters? Thats a lot of trips. Boned out, I would say 6 trips is about average.
You're right about hiking meat out of a swamp, it sucks...but moose live in swamps.

I know guys that won't shoot one unless they can get their plane to it. Then again they don't shoot many either. Being mentally prepared is a bigger part of it than being in top shape. know your limitations and stick to them, all I'm sugesting is not to set the bar too low. A mile isn't that far...
I've only gutted one moose, and didn't think it was that bad compared to an elk. Gutless is the way to go if you can. The one we gutted was due to the fact we had two down about 200 yards appart over a mile from camp.
This one died in ankle deep water and about 2.5 miles from the landing strip... It wasn't all swamp getting back luckily, and didn't kill me packing it out either.
