Coming from their recent travels in Lombardy, Anne and Jim chat about Leonardo da Vinci's notebooks. Why do we keep a notebook -- for ourselves? Our contemporaries? Posterity? Leonardo (who was often commissioned by the Sforza's, the ruling family of Milan) is arguably the most famous polymath of all time, painting, writing, designing inventions, even working as an arms contractor! We also talk about Milan, a lively and exciting modern city, as well as Leonardo's birthplace in Tuscany.
