erIC• an • • IC urIS The Camp Springs Community Garden Project in Camp Springs, Maryland, has a motto that rings true for all community gardens, and in fact, all gardens in general: "Gardening is down to earth." There is something about kneeling in the rich brown earth, with your friends and neighbors and the sweet smells of the garden sur rounding you, that awakens the senses and brings an inner peace to the soul. Community gardeners of all ages reap both intangible and tangible rewards from their gardening projects, including a sense of community, an appreciation for the environment, horticultural therapy, nutritious and less expensive food ... and the list goes on.
