The experts are forecasting more muted fall colors than in recent years, but the reds, oranges and purples are still alluring enough for you to embark on this self-guided driving tour.

Brochures, a map and directions are available at libraries, community centers, the Loudoun Convention & Visitors Association and area businesses. Free. Sponsored by Loudoun County Department of Economic Development. 10 a.m.-4 p.m. Saturday and Sunday. 866-771-7697 or www.loudounfarms.org.
