Kingpuck, most hunters do not pack a ton of ice in advance of a deer down. Some may, I have not seen it. Instead, simply get the hide off your game, get air to circulate around your meat. Get natural cooling started. Often game is hung at a camp in shade for a day or so if temperatures allow. If it is warmer out, get someone to town for multiple bags of ice to hang around your deer. IMHO, temperature is just too unpredictable to expect to need ice in advance of your kill.
So after the shot...You've gutted the deer. And you're two miles in the backwoods. Alone.Do you just grab the antlers and drag it back to your car or cut it up there? How do you carry the meat? another backpack?
