How are you planning on getting an elk out once it is down? Take care how far back you are hunting if you don't have a packer lined up.
Most completely underestimate what it takes to pack an elk out on their back until they have done it. Realistically, if you are in good shape, strong, have endurance, and don't have any feet, knee, or hip problems, you can bone the average elk and pack it in three loads. Some might pull off two, but in steep country you stand to do some back or joint damage. In an early season hunt, you will have time limitations in terms of temperatures and possible loss of meat.
