After several days in Tehran I can only say cities in super heavy category (> 15 million) are hard to go about... but for half a Euro you can ride the bus 35 times or the subway 5 times. In Tehran there is place for bivouacking on every sidewalk around the gardens. If the worst comes to the worst there is the space before the tomb of Imam Khomeini. The former embassy of the Great Satan - America - is painted with inscriptions such as "Down with USA", "We will make America face a severe defeat", “We stomp on America” in Farsi, and the Statue of Liberty with a skull for a face. My greetings to you.
