In a day-long event, called Imbutoto Olaigwanani, which is to choose an age group leader among the Maasai, hundreds of warriors, elders, women and children gather at a boma to celebrate the new leader. Here, about 250 guests are walking en route to the boma, carrying locally-brewed beer in jugs and crates of soda. Warriors have been preparing for the day all morning by covering their faces and hair with red ocre (dyed animal fat, performing traditional songs and dancing.
