Iso, that wouldn't be a black cow with a white face would it? If so, your neighbor proabably won't miss her if you "take care" of it. That ole cow was about as spooky as the deer were.
I'm sure that you remember that deer season opens next saturday. Oh by the way, the only thing you will need for her is a bar-b-que grill, and a big bag of charcoal and don't bother with the carcas tag.
