To get to Bologna by car, we would be taking A1 through the Apennines. I'm wondering whether the drive would be more scenic than a train ride - although if we took the train from Florence to Venice I don't believe we wouldn't be going through Bologna.
Are there interesting things to see along the route that would make taking a car more attractive than taking the train?
We won't be staying in Bologna. It'll be just a place (this time) to catch the train on our way north to Venice.
