Great pics on this and the tehran thread. On my visits, I am always impressed by the cleanliess of the country compared to us. Do give us pics of mashad, if you visit there. I see the paykans are still going strong.
An interesting thing about iran is that people also use their private cars as taxis. If you hail them and they are going your way, they would quote you a fare. Happened to me many times in tehran. But everytime they found I was visiting from Pakistan, they would give me a free ride. It is a wonderful country to visit and great people to meet.
