Any way you can.
There is no really right or wrong way.
pole, cart, buggy, bike, trailer, wheel barrel, whatever it takes.
now i live in super flat swampy, marsh type areas. Then inland the green briars can grow into like impenetrable walls. Or the mud is waist deep so any wheel type carts are out, jet sleds are ok but they suck on dry ground.
at least the one i had did.
So with that said i use a long aluminum pole like a pool skimmer pole if i need to drag long distances
The leverage it gives you makes it pretty easy to haul a deer out.
thats my go to way but like i said whatever works best for the individual.
really depends on the terrain your hunting in.
But, as i always say what works for one may not work for another and vice versa.
Truck , car, or whatever make it work.
front seat back seat, trunk, roof , wherever you can flop it lmao .
