Kathy tries to get truffle hunters to reveal their secret hunting grounds. Then it is time to attend the World Truffle Auction. We visit Cascina Bruciata vineyard to learn about the hearty wines. Piedmont is also home to hot springs, and Kathy goes to Lago delle Sorgenti to find out about the unique medicinal qualities of these baths. We also visit Lake Iseo to see fine Italian boat making.
