On Friday, October 29 Foster City Preschool held its annual Halloween party. The children came dressed in their Halloween costumes. Batman made an appearance, as did Superwoman, Minnie Mouse, Spiderman and a space cadet - as well as a host of witches, ghosts and goblins. Facial masks were worn as an essential component of every costume, and seemed appropriate to the occasion. There was a grand costume parade followed by treats, rather than tricks, for all participants.
