Nepalese army personnel ride through a frame of fire to show their skill during the "Ghodejatra" horse racing festival, which is organised by the Nepali Army, in Kathmandu, April 3, 2011. According to local mythology, racing horses and trampling on the 'Tundhikel' field would stop the demon Gurumapa, who is believed to be living in the field, from coming out and stealing children from the city.
