In Fairfax County, sheep mow lawns, beekeepers remove misplaced swarms and gardeners teach the community.
The Town of Vienna will feature organizations that do all that and more at its annual Green Expo at the Vienna Community Center (120 Cherry Street SE). Sponsored by the town’s Conservation and Sustainability Commission, the expo is set for 7 p.m. to 9 p.m. Thursday, April 18 — four days before Earth Day.
