Rostam Kalhor, head of Iran's skiing federation and coach of the national team, instructs his sister Marjan, the first Iranian woman to enter an Olympic ski event, during a grass skiing practice at Dizin Ski resort 70 km (43 miles) northeast of Tehran August 26, 2010. Skiing down a grassy mountain in the middle of summer is not the only unusual thing about Kalhor. She is also a professional, a rare thing for a woman in a male-dominated sport in Iran.
