If your thinking pack frames, a good tip is when loaded up, rest up by backing up to a tree and leaning on it.
Its easier than shucking off the pack and then, after resting having to strap it back on and rise up again with the weight.
A couple of "walking staffs" cut from small saplings, will help shift some of the load from your ankles and knees to your arms and upper body.
It also aids balance in rough country.
In Australia, we dont have Elk, we have Sambar, which are a large deer, not quite as big as Elk.
A common method is to skin along the back bone and remove the fillets and place in a pillow case.
Gut the animal and take out the eye fillets, place in pillow case.
Remove the back legs with your knife, take your time and feel around the hip ball joint, and remove the bottom of the legs at the hock joint.
Leave the skin on to keep the meat clean.
remove the front legs, leaving the skin on and taking off the lower leg at the hock joints.
Each leg is one pack load. You have almost all the best cuts of meat, in neat and manageable loads.
If you take a bull, the only change is to cape him first, which means another two game bags for the front legs.
If you take the animal in the afternoon, there is a fair chance of running out of daylight.
Some game bags and rope, to haul what you cant manage before dark up into a tree out of reach of other animals could also be handy.
