The Washington and Old Dominion Trail (W&OD or "Wad") is an excellent recreation trail that runs through the Northern Virginia counties. The 45-mile trail is completely paved with nine foot wide asphalt and has a yellow painted center line. To run the whole trail and back means you're looking at a 90-mile trek, but it can be done over the course of two days thanks to the hotels and bed and breakfasts along the trail. The only real complaint from bikers is that there's much traffic most of the time due to the Wad's immense popularity.
The Virginia Wine Expo is the oldest celebration of its kind on the East Coast and is regularly attended by wine aficionados from all over the country. Sixty of the state's top wineries are on hand to display their wares, but this celebration goes far beyond just tasting some of the best wines from the various participants. There are also seminars, cooking demonstrations, live entertainment, gourmet food and an outdoor art and craft show. The event is held every September.
