RE: proccessing your own deer
We do it ourselves. It's cheaper and you know exactly what you are getting. Also, some of the butcher shops have deals where they "Cache" deer. Meaning you drop off your deer, and you pick up meat from another. No way! I want my own meat!
We mostly cube it up and make sausages, etc. We keep the tenderloins and back scraps. We did an elk cow once, and might consider a butcher the next time.
