My kids noticed that the pigs were gone. They've got an eye (or three) for details. Several times a week we drive through an agricultural area, lots of cornfields and cows and the occasional tractor. They (whoever they are) keep pigs. There is a little compound of two-doored huts with fences around the houses and a larger fence around the whole area. They start out smallish in the Spring; they looked about the size of a standard poodle. By late August they were big. Not Volkswagon Bug big but I've seen smaller cars. Every time we drove by there were sightings, naming and disputation of names, and consideration of changes in their sizes.
Today, they noticed.
There are weeds growing in the compound and two of the gates had been left open.
