... I know this is an old thread but I've got to reply. Actually most hunters do live in the field. An average deer camp is one or two weeks while a bear hunt is longer. Mountain lion or mountain sheep camps are several weeks as are elk hunts. Certainly these are the shorter hunts as anyone going for more exotic game would need to go to Africa for a lengthy safari....
I've done several same-day Elk hunts in Montana where I hiked in early in the A.M., hunted for a few hours, made a kill and packed two loads of meat out before nightfall. The second load was the last because I brought my hunting partner with me to help with the hard work and nothing got left behind

A good friend of mine recently did this with a longbow he had made himself - drove an hour or so from his house in the very early morning, hunted up the mountain for a few hours, made a kill and got all the entire carcass out on his own before dark. He could hardly walk the next day he was so stiff, but he couldn't stop smiling either...

I've done very similar single-day hunting for Whitetail in Alberta and Saskatchewan (the Saskatchewan whitetail are bloody huge incidentally

Most UK and European hunters go out for the day, although in some European countries they may spend a few days camping or in a cabin while hunting. I would say that the vast majority of my hunting is a single day affair, where you do the whole "there and back again" between dawn and dusk.
