Santa Claus, above, waves to kids of all ages as he rides into downtown Concord on a fire engine at the city's official tree lighting and Mayor's Sing-Along on Saturday, Dec. 1. Crowds lined the streets around Todos Santos Plaza for the annual event, which also included carriage rides and culminated with the lighting of the tree. Also at the holiday kickoff, the Concord Salvation Army Band, top, provided music of the season. The following day, the Concord Historical Society opened the Galindo House, the city's only permanent museum. Dozens of visitors toured the 1856 home, the oldest wood frame Victorian farmhouse in Concord, which was decorated for the holidays, including the festooned dining room, left. The home was originally occupied by Francisco Galindo and his wife, Manuela Pacheco, the daughter of Don Salvio Pacheco, one of the city's founding fathers. The museum will be open from 1-4 p.m. Sundays and Wednesdays.
