What: Trick-or-Treat So Others Can Eat Food Drive begins October 27 when Bon Air welcomes costumed kids, families and pets to its Halloween Bash. Guests can join the annual food drive by bringing canned foods to fill the SF-Marin Food Drive bins located throughout the center in exchange for a trick-or-treat bag. Then trick-or-treat at Bon Air’s restaurants and shops.  Enjoy face painting and balloon twisting and decorate pumpkins at Bank of Marin.  All pets are welcome to join the Woodlands Pet Food & Treats’ pet costume parade at 1 p.m.; costumed pets and their people can capture the silliness by posing for free pet caricatures.
