Bring little ones to enjoy the "Frida Kahlo: Art, Garden, Life" exhibit at dusk, when your family can snap photos with larger-than-life skeletons, dressed up in celebration of Dia de los Muertos. Con Edison will provide flashlights to help find your way along the Whole Foods Market Trick-or-Treat Trail, where you'll hear ghost stories and encounter giant pumpkin displays on the Mitsubishi Wild Wetland Trail. Timed entries at 6:30 and 7:15pm, advance purchase recommended. All ages.
