Not exactly "roaming in the town", but just last week I was talking with someone that remembered how - in the late 1950's or early '60's - her family (in Tuscany countryside) had usually three or four pigs that were routinely brought (by her, at the time 8 or 9 years old) to the nearby woods and it happened more than once that one of them would flee and get to the village, and be later brought back by this or that neighbour.
