Week Ahead: Costume Contest, Adult Play Time, Winchester Mystery Tour

Here are three can't-miss things to do this week in Santa Cruz and beyond:

Thursday Halloween Costume Contest: Stop by Rebecca Stark Photography studio in your costume on Halloween. They'll be photographing all trick-or-treaters in their costumes and posting the image on Facebook. Person with most likes by midnight gets $100!

Winchester Halloween Mystery Tour: The famous flashlight tour of the Bay Area's original haunted house. Guests tour the "rambling, mysterious mansion at night with only the moonlight, a souvenir flashligh and their imagination to provide illumination through the bewildering" property, according to the event's website.

Friday Holy Cross Parish Hall, 6-9 p.m.: Come get a behind-the-scenes look at what some busy exhibition planners have been up to at the Santa Cruz Children's Museum of Discovery (MOD), an emerging children's museum. Munch on sumptuous appetizers and mix your own cocktail at our Muddling Bar. Sumo wrestle with LEGO NXT robots, make mini rockets, fly remote control helicopters around the room and join in on countless engaging science activities that will make you feel like a curious kid again.
