Funny how I am Iranian and I've seen less of Iran than you. Amazing story. It was very interesting to see your see a "safe" place and enjoy the sights/food.
You notice people flocking to Mexico or even India. A place where murders, kidnappings, rape, and violent muggings are very common. Iran is relatively safe to these places.
I will probably backpack through Iran next year. Can't wait.
