The mother of the motorcyclist mentions that she lived through the Bel-Air fires. The Bel Air Fire was a disaster that began as a brush fire on November 6, 1961, in the Bel Air community of Los Angeles. 484 homes were destroyed and 16,900 acres were burned. The fire was fueled by strong Santa Ana winds. The fires resulted in 12 non-fatal injuries and no fatalities. As a result of the Bel Air Fire, Los Angeles initiated a series of laws and fire safety policies. These included the banning of wood shingle roofs in new construction and one of the most stringent brush clearance policies in the US.
