Nice! Just looking at that hog on the back of your ATV makes my back hurt.
Not to mention the 50 yards or so I had to drag that sucker before even attempting to put on the ATV.
It honestly wouldn't be that bad if you could get your hand around their legs to grip but these big boys got some large hoofs!!!
I have made a "drag line" just for this purpose. Take a 5-6 feet of rope, loop it around the big boys' head and maybe one front leg, take the other end and run it through a chunk of heavy gauge PVC and tie it off, like ski rope handles, and then drag away! This way you're dragging the piggie WITH the grain of its hide, and the handle gives you a few options on how to grip it and pull it.
