On the front lawn of the Marvelwood Drive home of Ted Baldwin and Barbara Geller, a young giraffe stretches for food. Nearby, its towering parent surveys the landscape.A stork cackles while a giant black spider meanders through the low-growing, bamboo-like grass. All are neighbors in the Baldwins' free-range residential paradise. Some homeowners adorn their lawns with inflatable Santas, wicker deer, and other holiday displays. In the spring, others put out whirligigs or garden gnomes. A few, however, defy the status quo.
