Children can experience a non-scary, natural alternative to traditional Halloween events at the annual Nightfall event in the Chicopee Woods. Elachee Nature Science Center will provide a fun and educational event from 5-8 p.m. Oct. 19 by escorting participants through the woods to meet costumed naturalists with treats and stories to share. During the “Trick or Treat” trek, storyteller Toni Hurst will spin funny and not-too scary stories by the light of an October moon.
