If for no other reason than the health and well being of our family and ourselves, we should devote what is necessary to this end. The Soil and Water Conservation District program is one of the few direct 'cause and effect' organizations that aims exclusively for that goal. My experience with the Northern Virginia SWCD has been one of the most satisfying volunteer pursuits I have had. The Prince William SWCD offers another facet of that experience that I would like to explore."
