[IMGCAP(1)] This American flag/Constitution combo is hanging in a basement. And it’s not in the basement of the National Museum of American History, since that’s under renovation. So where is it? Check back next time for the answer. [IMGCAP(2)] A flag was flying much higher over the construction site in last week’s Lost & Found challenge. That site was at 300 New Jersey Ave. NW. The photo was taken from a perch at the nearby Hyatt Regency Hotel.
