I can't imagine dragging a deer in from the field that hasn't been field dressed. I don't understand that at all.
Where we hunt you don't normally have to drag them anywhere unless it's out of a swamp or bay to the 4 wheeler or truck. Load them up and take-off.
We live in a rental house that is about 1/2 the size of what we need. The garage is packed with stuff and there really isn't any place to make it happen the way I would like. We are in the process of planning our house and the build. A complete area dedicated to processing and hanging game and fish is going to be part of it complete with butchering station, cooler, meat processing and washdown. Yeah, I'd rather process my own but right now its easier to take the entire animal and let the processor I know do it for me and we know that the deer we take to him are the deer we get back from him.
