"Thousands of people uniting over one cause its one day for one people but its our whole life we pretty much revolve around autism or behaviors from it so its really rewarding to see so many people, friends and family and resources that are really recognizing Autism Now," said volunteer Jenny Frazier.
All funds will go toward autism research. The event begins at 9 a.m. and will feature food, face painting and even an appearance from Elvis.
Participants work in teams, many of which have been fund raising more than a month.
