About 800,000 people every year make a visit to Plaza de Cesar Chavez in downtown San Jose part of their holiday tradition. Of course, it's not to visit the Plumed Serpent statue or relax on a bench overlooking the Tech Interactive. No, for five weeks spanning Thanksgiving weekend to New Year's Day, the two-acre park's biggest draw for nearly 50 years has been Christmas in the Park a kitschy and whimsical collection of animatronic displays, hundreds of decorated trees and a chance to visit with Santa himself.
