Just a couple of thoughts on deer prep:
I always like to hang deer before dressing (gralloching?). It is just easier as all the guts fall out - rather than having to be scooped out. At work, I don't have this option, as I have little time to devote to it. I do have the option of using rubber gloves at work, but have to be careful not to get blood on my uniform. I can dress a deer in about five minutes, it just isn't that hard to do.
If the weather is cold, like this time of year, I just haul the deer home and hang it. A deer can safely be hung over night with the guts still in the deer without any meat contamination. If it is a small deer, I will not even gut it, as there is little meat of consequence beside the shoulders, haunches, and back straps. The neck meat is so full of sinew and tallow, it is hardley worth the effort unless you are going to make stew. With a larger deer, I take the flank meat and neck meat as well.
It is best to let the deer partially freeze before butchering. If you do, you can remove the back straps with your hand, no knife needed. This state of partial freeze also makes for much easier butchering.
Butchering is not rocket science. Just bone out all the meat, remove all tallow and sinew, and make all your cuts of meat across the grain. The bone, tallow and sinew will give your meat a very wild taste. Never take your deer to a butcher who is used to doing only cows and pigs. On a large deer, the best cut is the tenderloin. On smaller deer, the tenderloin is very small. The next best cut of meat is the back strap (chops in a cow). Roasts can be had from the back straps and haunches. Shoulders or haunches can be roasted whole, but there is an art to it.
If you hang a deer too long in warm weather, the meat will start to putrify starting at the joints. Just cut away the bad meat - it is quite noticeable - the rest will be fine. When your meat starts to get a greasy feel - even if it's been in the fridge (not freezer) too long - it is starting to go bad. Time to cook it up, or throw it out.
On the other hand, my grandfather used to say you could never get sick eating raw meat - no matter how far gone it was. He said it was cooked meat you had to watch out for. I'm sure he would have known, but I've never cared to find out.
One of our neighbors, when I was growing up, would hang his (dressed) deer until the hides turned green. I've no idea what the object was, but he liked them that way. so saying, I'd better get out and skin my last deer - which has been hanging since November 12.
