I finally saw one! Well, not one, but six babies and their mother.
2:30 in the morning, driving home from a friend's birthday dinner (a great dinner, by the way, with much depleting of their wine cellar) and these little piglets appeared out of the vines and sauntered across the road with mom bringing up the rear. You could almost hear her saying, "come on, come on, move it along."
It was so amazing to finally see a sanglier in person. They were much more delicate looking than I thought.
But now we feel guilty, as just last week I made a delicious Tuscan Wild Boar Stew from The Italian Farmhouse Cookbook out of one of their relatives. I guess we should apologize...
