You can't let the drag concern you, but you should plan for it.
As others have mentioned:
- A game cart is great if you have a real long trail or road you're not allowed to drive down. I don't own one, but used them and even wheelbarrows. Work great!
- A bike also works for the above. You put the deer on the bike, seat in the chest cavity, antlers or head tied to handlebar and walk them out. Did that with a friend a couple times. Works great!
- Sleds help a lot. I just use cheap walmart kiddie sleds. Depending on the terrain you drag over, they can last anywhere from one drag to an entire season or more of dragging.
As far as quartering goes, I've quartered big bears for clients so we can pack them out. There would be no other way to move them.
It can be done even more easily with a deer. The only issue is, you'll obviously need a way to carry the quarters, so you have to have a decent sized pack that can handle some weight (and not be jam packed with a bunch of gear already).
You could treat it more like backcountry hunting and bring in game bags (they weigh next to nothing and take up a small amount of space)
Once the deer is down and dressed, quarter or even debone the meat in the field and hang it in the game bag from a limb in a shady spot. This lets it start to cool and keeps bugs off of it. (bears are also a big problem where I hunt, so I'd be afraid to leave my trophy accessible to them.) Then take all of your gear back to the vehicle and come back with your "game haul pack". Pack up for the haul out. WIth a deer, you can probably get it all out in one trip, including hide and antlers.
There are tons of great packs on the market, my friend in Idaho uses a Tenzing 5000 or 6000, and it's NICE....but if price is an issue for you like it was for me.... I use the USMC issue ILBE main pack to haul game. The new packs are the FILBE, but since the Corps just switched to the FILBE, they are more costly and harder to find. The ILBE is pretty plentiful and cheap on ebay. And even though it's heavier than the Tenzing, it seems to be built with more durable material.
If you didn't want to leave the meat behind on the first trip, you could always carry your hunting gear in the ILBE (though it's large and excessive for the small amount I carry) and when you down an animal, quarter, debone, pack it up and take it out. You'd have to come back for whatever gear you may have to leave behind, but in an area like mine with so many bears, you would be better off leaving gear instead of meat.
ONE NOTE for quartering: KNOW your States regulations on "proof of sex" requirements.
Also, search for "gutless dressing". If you're going to quarter the animal, it skips the unnecessary step of gutting. (If it's extremely hot, you may want to gut anyway to get that body heat dissipated as quickly as possible.)
My knife of choice for this is the havalon piranta (I think that's the name, I bought it before they became popular)....Carry extra scalpel blades and you never have to work with a dull knife.
If you shoot the animal of a lifetime, you'll be floating on air the whole way out anyway! So distance won't matter.
Good luck.
