When Shane Grammer's old church acquaintance Clayton Butler asked him to paint a mural in Phnom Penh, Cambodia, he didn't think twice. Grammer, a 38-year-old artist currently residing in Roseville, completed similar murals in Peru, Mexico and Brazil, sometimes teaming with urban kids on the pieces. "I'm ecstatic; I love that," Grammer said. "I've offered stuff like that before, and people are just busy or don't do it. So when I'm asked to do it, I'm like, 'Yeah, I'm there tomorrow. Where do I sign up?' " On April 12, he will be leading a team of six to Cambodia to help Agape International Missions, where Butler works, to help end child sexual slavery and help restore hope to its victims.
