The two bulls I've taken in Colorado were both quartered and taken to a local cooler while the rest were finishing their hunts. Once that was done, we had about 14 hours to home from there. I had a big blue tarp and made a cooler out of it. I laid it in the truck bed, then laid blocks of ice on the bottom, then put the game bags with elk meat on top of the ice, and folder over the tarp and tucked it under securely. The meat was cool when we arrived home.
