Just put it on ice and get flying. I properly butcher and freeze the meat once I am home.Thanks all for the responses. Right now I am leaning towards flying reason being is time is going to be limited. I have 5 days total to get out and back. Thinking of leaving Thursday red eye direct flight to Denver, hunt mid morning and evening. Then fly back Tuesday night. If I drive coming from Michigan it is going to be minimum of 20 hours solo.
My bigger concern is now how to get meat back. Early this year I broke down and deboned a deer from 10pm-2:30am in a hotel prior to our departure home the following day in a hotel. My guess with the elk I could do the same, but getting it frozen is going to be the trick.
