This is the ninth year for the parade, and participation has spread by word of mouth, she said.
The parade starts at Idyllwild and Santa Clara avenues in Redwood City and travels down Himmel Avenue to Selby Lane School in Atherton.
Ms. McCain is a past president and founder of the education foundation associated with Selby Lane School.
At Selby Lane there will be a bake sale to benefit the Woodside High School music department.
The Woodside High School marching band, as well as vehicles from the Menlo Park Fire Protection District and the Sheriff's Office, join in the parade.
Kids are encouraged to bring musical instruments and boom boxes "to make some noise," Ms. McCain said.
