I had the opportunity to visit Northern Italy in November. The weather was surprisingly fine!
Sirmione is a lovely peninsula on Lake Garda, way up in the North of Italy. It is well-known (at least to Classicists) for Catullus' poem 31. It's a celebration of the beauty of Sirmio and the joys of homecoming after a stressful year in Syria. http://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.02.0006%3Apoem%3D31
Verona was a city with a wonderful mix of Roman and Medieval architecture. About a meter below the Medieval buildings and roads lie Roman roads. The large amphitheater still hosts operas. This blend of the modern living out of the ancient was fascinating. Drinking a late night coffee under the Roman Gate, a gathering spot for local Veronese, was a particular pleasure. On the outskirts of the city are fortifications and government buildings built by the Austrians (I think) around the time of WWI.
I flew ryanair out of Bergamo.
