If you want to participate in a unique part of Cape Cod’s upcoming holiday season, get your map of the Sandwich Giants and plan for a night of magic and joy, driving through the town and along Route 6A, seeking and finding each special sculpture along the roadways. It’s a tradition that began when the first Giant, titled The Glassblower, was created by Michael Magyar, owner and artisan of The Glass Studio in Sandwich, over 25 years ago.
