Virginia Landmark Contest Back By Popular Demand

I've been flooded by numerous e-mails (three can be considered "numerous", right?) requesting the Virginia Landmark Contest be resumed.

Never one to disappoint my readers, I searched through my remaining photos and found Virginia Landmark #15.

Identify the location, and you will win a bathmat made from recycled Larry Sabato toupees, with matching seat cover. (Proprietor of this site not responsible for color mis-match or decorating faux pas which may result from use of prize.)

UPDATE:
Mary Rives Brown is now the proud owner of a matching bathset (in a drab brown). She has correctly identified the City of Martinsville's Hydroelectric dam on the lower Smith River, just south of the City Limits on US 220.
