eh...I have never entered a formal agreement on splitting the animal equally. Sorry I'm not giving up 1/2 of my elk to my buddy I'm hunting with. If someone shoots one, expectation is everyone helps to pack out. Or at least everyone I hunt with would offer to help if needed. Knowing I would return the favor. If I get called at 8pm to help my buddy recover his deer 1hr away...I just do it if available and expect nothing in return. What the hell is the point of shooting a cow for meat then splitting it 4 ways? Or 4 guys in camp I kill a deer an no one else does now I have 1/4 of a deer? Nope.
Hell I shot and elk, moose, and a couple deer this year and feel low on meat right now feeding a family of 4 (soon to be a 5th once the baby eats solids).
With that said...I will offer or gift them some processed sausage, steaks, snack sticks etc as a thank you. I have also killed does and gave them to people that wanted them
