Hickory Hill / Description: In the heart of one of the fastest growing regions in the United States, Frederick is within an hour drive of Washington, DC and Baltimore. Frederick has become a magnet for high-tech companies and is home to the 5,700-acre Catoctin National Park, the site of the Camp David Presidential Retreat. Hickory Hill is only minutes from some of the area’s largest employers, Fort Detrick and Frederick Memorial Hospital, in addition to five retail strip malls. Since 1970, Frederick’s population has doubled in size and was ranked fourth among the Maryland counties with a growth of 30 percent from 1990 to 2000.
