Historic Leesburg, with an old town feel, is at the heart of one of the fastest growing sections of the country. Loudoun County, Virginia is the second fastest growing county in the United States in 2005. Leesburg is the County Seat of Loudoun County. With several Virginia wineries, outlet malls and lots of open space a short drive from the center of Leesburg, there is much to draw visitors there.
Up until only a few years ago, Leesburg was quite rural. Recently, large tracts of housing developments quickly replaced many of the historic horse farms in the area.
Leesburg is less than an hour drive from downtown Washington, D.C., the nation's capitol.

The only redeeming and truly worthwhile (i.e. unique) travel experience to be had is to visit downtown/old Leesburg. The center of Leesburg is relatively small, walkable area near the courthouse (at the crossing of King Street and Market Street). There are a number of shops and restaurants, as well as the town buildings, within about a quarter of a mile.
First Fridays -- the first Friday of every month shops stay open late providing a chance to shop and explore downtown stores in a street festival-like atmosphere.
Flower and Garden Festival -- downtown streets are closed while local vendors provide insight into gardening and landscaping products and ideas.
Leesburg Court Days -- one weekend in August, Leesburg goes back in time more than two hundred years to provide visitors with the flavor of the beginning of colonial times.
