Last month a parade drew over 80,000 people to the Sacramento Valley. Before any floats passed, people in colorful clothing and turbans sprinkled water on the street and swept the concrete, cleansing the route. They were celebrating a holiday of the Sikh faith: the 500-year old religion from India’s Punjab region. This gathering in Yuba City is the largest of its kind in the U.S., because Sikhs have lived in this farming community for over 100 years.
