Even in normal weather conditions parading up and down Tehran's more fashionable streets is a kind of pastime for Iran's entertainment-starved youth. Now, with Tehran in the grip of heavy snow, the city's youth are taking the opportunity to enjoy another kind of automotive entertainment.

Where I live, in the foothills of Mt. Tochal, there's a wide plateau where last night dozens of cars were pulling hand-brake turns and spinning in circles to the tune of loud techno music. A kind of semi-organic organisation had emerged with cars parking to block off both ends of the street. Plenty of the partygoers were quite obviously drunk and the festivities were quite obviously going to continue for some time into the night. I was on my way to work and didn't have my camera on me but next time I hear screeching from my apartment I'll run down to try to capture the atmosphere.
