Being able to do it and doing it are two different things.

I think for most hunters living in the city or suburbs who hunt in the country it's more of a convenience type of thing.

Not sure how easy it would be to process a deer out of the back of your truck in the middle of a field? You could get it in the cooler and eventually process it once you get home, personally I think alot of guys would rather get the meat cooled off sooner and processed sooner than keeping it cool for a few days or a week then doing it themselves once they get home.

Also depending on what suburb you live in, a neighbor sees a full deer carcus hanging in your garage might end up with the police on your doorstep.

If/when I have my own farm and walk in cooler, I'll definitely be processing my own game.
