GWB,
I have always field dress deer before moving them. It is just the common way here plus why bring the guts home? However it is very common around here for folks to wait till they get home to clean turkey and small game as well as fish. I know some people though who actually carry bread bags and just peal the breasts out of birds and just bring meat home. I don't hunt small game or fish so I do neither. I also gave up butchering my own deer once I left home. Most of the time my deer are spoken for so I take it to the butcher shop and have it cut up the way the person wanting it likes. This year was the first year in quite some time I kept a whole deer for myself.
