City officials say the big turnout highlights how important the city's involvement is. Randall Cooper, Fresno Parks Department, says "The need is real here. You can see it in the number of children here. There's lot of kids who need things to do in a positive manner."

City leaders say they want to give kids something to do at school, in the evening, and on the weekends.
