On Saturday morning at 9:30 a.m., a small circle of people, bundled in scarves, hats and rain gear, stood in the wide median of Encinal Avenue near High Street on Alameda's East End. "There was a village here until 1847," said Rebecca Holder of Alameda's Multicultural Center, one of 30-plus walkers participating in Day Four of the 10-Day Shellmound Peace Walk. The walk passed through Alameda Friday and Saturday.
