Awesome! Thanks for your responses all. I'm not sure how we got onto Hoboken, and yes I did indeed want to know if during my layover I could get out and see some of Pisa. I am sure there are lots of sights to see, but given that I have never been there and have a few hours, I would indeed like to see and photograph the tower and the cathedral - why not, its better than sitting in Pisa airport I am sure
