My husband and I have been to Italy 6 or 7 times and have seen so many lovely things. In October we plan another trip, starting in Venice and then heading down to Tuscany. I'm thinking about stopping in Bologna on the way and taking side trips to Parma and Reggio Emilia. Are they worth a driving trip, rather than just training to Sienna and picking up a car there? What's the incentive, other than the wonderful food? Thank you for your help.
