You forgot to say if you made the tour on time! What a cliff hanger! Thankfully I saw the answer in another comment, glad you made it. :o)

I went on a road trip last summer, and as a foreigner was thoroughly confused when driving across Alabama to Georgia, and the time changed. Then I got even more confused as I was driving in Tennessee and Kentucky, and the time just kept changing.

I think I understand time zones in theory, but in practice I always mess up and get it wrong, and confusion and hilarity often ensues. :o)
