Aside from the White House, the United States Capitol building is the most visited building in Washington. This incredible building with its regal dome and classic architecture symbolizes democracy to everyone who sees it. The view from the front steps is like nothing else, so make sure you have your camera with you. Tours are available at the kiosk on the southwest side of the Capitol, and are free of charge, on a first-come, first-served basis. Plan to get there early, as there are always plenty of people in line for this extremely popular attraction.

Considered by many to be the ultimate must-see museum in DC, the United States Holocaust Memorial Museum is nothing short of an emotional and educational experience. When you arrive, you are given an "identity card" of a real Holocaust victim that deeply personalizes your trip through the various exhibits. You'll view an astounding collection of film clips, photographs, artifacts and unflinching first-hand accounts. There's even an exhibit for the kids that treats the subject matter in a highly sensitive manner; this exhibition will inspire questions and answers that will no doubt lead to a better understanding of this horrible passage in our world's history.

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.
