More than likely if you found them, they'd have a refrigerator full of beer, maybe a little meth laying around somewhere, with a cigarette in their mouth. Those folks are easy to throw the book at. I'm guess I'm figuring they wouldn't ever go to the trouble to really field dress something as large as a cow.
Funny story fairly unrelated. Several years ago I was out with my father-in-law feeding one early sunday morning. Saw a feral hog in the road ditch and I shot him. We usually don't bother to eat them. We drove up to one of our lease places. There was an old house on it rented by a particular sub species of white trash. Trying to be neighborly (for what reason I don't know), my father-in-law made me go to the back door to see if they wanted the dead pig. The wife comes to the door. I explain to her why I'm there and ask her. She answers "*** yes we want him!". Then she hollers back into the house "Such and such, get your *** out of bed and go with Alan's son-in-law." Here comes her husband, still in his sleeping clothes and fuzzy house shoes, obviously hung over from a hard Saturday night. We go drag the pig to their back yard, where they hang it in a tree, and momma starts to work on him with a pocket knife. I can still picture it to this day. That wasn't exactly what that guy felt like messing with on Sunday morning. You'd have thought we gave that woman a million dollars.
Of course when they finally moved off they left about 5 old cars sitting in the yard of that house plus all kinds of other junk we still have to maneuver around.
