The Vassar Cooperative Day Care Center, a co-op started by Vassar families, celebrated its tenth anniversary with a party and concert in the Villard Room. Carol Gainey, director of the co-op, described the day care as “a family affair:” some parents spent their lunch hours at the co-op, and there were bi-annual events where parents would help fix up the center, followed by a picnic.      The Miscellany News
