Seriously, We Need a Cow

We have friends staying with us while they look for a home nearby.  We love having everyone here, all of them, but the speed at which we go through milk is astonishing.  We have six kids in the house, all under 10, so you can imagine how much we drink.  Add to that my cereal habit (still, can't help it), and we're going through nearly eight gallons of milk a week.  It's amazing.

Now, how to get a cow past the City Code Enforcement???
