FAIRFIELD — Trick or Treat on Safety Street has a new costume this year — “Halloween on the Green.”

The traditional event, sponsored most recently by the Fairfield Kiwanis Club, allowed costumed children to trick or treat in downtown Fairfield at participating merchants, as well as on Sherman Green, where they would find a police car, a fire truck and probably the scariest thing of all — politicians.

This year, however, the event, which will be held on Oct. 30, has been moved to the Fairfield Museum and History Center commons.

In addition to trick or treating, the all-day event will also feature games, crafts, and entertainment. The event is free and open to the public; it is recommended for children up to age 12.

From 10 a.m. to 4 p.m., the museum commons itself will don a new personae, as it is transformed into a Halloween village, with displays in the Victorian Cottage and barn, the Sun Tavern and the Old Academy.

A costume parade for humans will take place at 2 p.m., but there will also be a costume parade for man’s best friend. Registration for the pet parade starts at 10 a.m., with the parade at 11 a.m. There is a $5 entry fee per dog, and all will receive a free treat thanks to the Chamber of Commerce. The first 50 dogs to register will get a free bandana, and there will be prizes awarded at the end of the parade.

And the activities won’t be confined to the museum commons. The Chamber of Commerce will hold a Market on the Green during the day, in front of Old Town Hall, and attendees can carve a pumpkin on the front lawn of St. Paul’s Episcopal Church.

Food trucks will be site and there will be extra parking available at Sherman School.

Event sponsors include the town, Newman’s Own, TownVibe/Fairfield Magazine, Lesko 7 Polke Funeral Home, Stew Leonard’s, Chamber of Commerce, Knights of Columbus Council 2616 and the Father Coleman Foundation of Fairfield, Inc. Bags to hold all the loot collected will be provided by Willows Pediatric Group and Kids First Pediatric Dentistry.

Entertainment throughout the day will be provided by Double Up Dance Studio, “Boby & Dave,” and Yoga with Maggie Taylor.
