Seriously consider the undertaking of harvesting an Elk without help, they are large animals, you need a lot of equipment (game bags, knives, pack frames, cooler, etc.).. to take care of your animal,
An awesome experience can turn into a nightmare when that Elk is laying in the deepest hole he can find, on his stomach, and trees and other brush keeping him there,
Rolling over an animal of that size, then tieing his legs out of the way, or however you process him (or her?) and getting it all out of the woods requires 6 trips for me alone, any help is appreciated.
I honestly feel that Elk hunting requires at least 2 people, one can do it, but he/she better know how to get the animal (meat/trophy/hide) out before it is worthless..
