did you try to go to the beautiful north of iran, the green caspian sea area. i lived there nine years and i'll be glad to lead you there. >> let me just -- before i do the last question, i want to just quickly remind you -- well, i'll do that last question -- i'll we'll talk about those books later. i didn't have enough time to go to the caspian sea. that was my first trip to iran. i went to iran in the last days of shah but i didn't have much interest of picking up all these issues. having gone to iran just for this brief trip last may, i want to go back. i just scratched the surface, obviously, and i just -- everywhere we turned there was interesting stuff and so many people in iran told me you got to get up in the caspian sea and the more lush area. it was a arid, high plateau we were in. it was just speckled with fascinating ancient sites and hard-working little communities and the great city we saw. >> well, thank you very much. >> thank you. >> this was wonderful. [applause] >> thank you. thanks. >> and we hope you go back. >> i'm going to go back. thank
