At my hunt camp, myclub has a cooler. I field dress before I put my deer on my ATV. I then bring it in to camp and hang it to finish the dressing and cleaning it. After that I will let it hang in our cooler for at least a week and then take to the processor.
Just about everything the guys have passed on is good info. For a long time I did all my own butchering and did waist a lot of meat. The pros do a great job and get all the meat that will go into my freezer.
And Welcome to the brotherhood of hunting my friend and good luck!
