Barrio Cafe chef Silvana Salcido Esparza turned 50 this year, and she was pissed. It wasn't the number of candles on her cake or years she's spent building her restaurant business on 16th Street — it was Arizona Senate Bill 1070. Esparza's been glued to the news and images of Arizona's Mexican community in all its lackluster glory on the big screen. "Oh, we have a vibrant community here," she says. "We just need a center for that community to really shine." So she started with her back wall. Esparza brought in El Moises to paint a mural, and then she was struck with a vision: a Calle of Murals. She set up a Facebook page, then an e-mail address, then a website. She has almost 20 artists and 500 Facebook fans. The first official "Calle 16" mural will go up in October. "They can't stop us," says Esparza. "I want the city to crawl back to us and ask where they can help."
