I have had three deer processed, the rest of them have been done by me, or me and Mockingbird. I do a better job at getting all the meat off of the bones than the processors, and I don't get marrow all over everything because I don't use a bandsaw.
I live in an apartment, and having killed deer right before breaking camp, have had to butcher in the kitchen. I quarter the skinned carcass in camp, and bring the quarters into the house. The neighbors know that I am not quite right, so they just nod to each other and say, yeah, here she comes with more body parts in garbage bags.
I have not tried aging meat by hanging a deer on the balcony yet.
