I'll be 70 years old next month and I hunt a wilderness area in Arizona mostly archery and mostly bulls. I've hunted this area for 44 years now and in that time I've killed one bull with a rifle, 17 bulls with a bow, compound, recurve, and longbow, and 4 cows with bow. Some have been close to a road, most were not. Many were around 4 miles, and many were when I was by myself.
Over time I just learned to use a light weight tarp and good game bags to quarter and then bone out the meat. I usually take o e load that I can comfortably pack, let's say 65 lbs and hang the rest in trees. It may take me 3 or 4 trips and some times more than a day but I can still get it done.
My method of hunting cows, which is mostly what I do now due to tag availability and my waining years remaining to draw tags, usually results in me killing big mature cows. And I do think about how to get them closer to roads, but in the end, I do whatever it takes.
