PHOTO GALLERY : Nights of the Living Dead at H & M Potter School

The halls and rooms of the H & M Potter School were transformed into a "Zombie Apocalypse" on Friday and Saturday night. More than 100 teachers, students, parents and alumni got gussied up as the living dead to raise money for the H & M Potter Parent-Teacher Association.

Somehow, someway, the drinking water became contaminated, causing anyone who imbibed to become a zombie. Suspects lurked on every corner. It wasn't pretty, as you can see.

The tour lasted between 15 to 20 minutes and included other less frightening activities such as bobbing for doughnuts on a string and outside displays on the school's front lawn on Veeder Lane.

"I have 100 percent of my staff volunteering," Principal Jeffrey Zito said. "It's amazing."
