Billy Gridley’s yard of zombies, spiders and ghosts scares up support for Healthy Waltham

At the end of a dead-end street in Piety Corner sits a Halloween display that is not for the faint of heart.

For 13 years, Billy Gridley has turned the front lawn of his home at 107 Marivista Ave. into a scene packed with zombies, jumping spiders, floating spirits and towering grim reapers. Animatronics, lights and props are placed throughout the yard to keep visitors on their toes.

Gridley started the display to entertain his son. It has since grown into a neighborhood tradition.

Gridley said he spent more than a month building this year’s display. It also held up through the nor’easter that hit Waltham Sept. 26–27.

The display still entertains the neighborhood, but Gridley and his wife, Jennifer, also invite visitors to donate to Healthy Waltham. The nonprofit works to alleviate health disparities and improve health outcomes for Waltham’s most vulnerable residents. Its programs increase access to healthy foods, provide nutrition education and create opportunities for physical activity for underserved and low-income residents.

Visitors can donate by scanning the QR code in the photo or visiting the Venmo portal.

Billy’s Haunted Halloween Horror is open to the public day and night through Oct. 31. Drop by, if you dare.
