After visiting Pisa, we decided to drive across the better part of Italy and head to Parma. We figured they made some pretty good cheese, and there would have to be something there. It was also in a good vicinity of some other places we could go.
The problem is that there's really nothing to do in Parma without some preparation. We arrived about 8 at night, and after driving around the city the next morning - we realized there really wasn't much to do. So we went to Modena instead.
