"I like it because it's kid friendly. You're not afraid to come out because you see a lot of kids here, a lot of adult supervision," parent Norma Rodriguez said.

Program officials said the numbers speaks volumes.
"Last year we saw about a 40 percent reduction in gang-related Part 1 crime for all 24 sites combined," said Alicia Avalos, the program's director. "It's true that people do feel safe in our surveys that we've done with the community member."
