Signs Must Come Down

Political candidates have until Dec. 2 to remove their campaign posters from signposts and tree boxes across the city. Posters must be taken down within 30 days of an election, under D.C. law. Candidates whose posters remain up after the deadline risk a $35 littering fine for each sign left in a public place.

Inspectors with the Solid Waste Education and Enforcement Program of the city's Department of Public Works issue notices of violation for campaign posters as well as those advertising goods and services.

The D.C. police department and the District Department of Transportation will offer free child safety seat inspections from 10 a.m. to 3 p.m. Saturdays through Dec. 18 at various sites.

Inspections will take place:

* Nov. 20 at 2500 West Virginia Ave. NE.

* Nov. 27 at 4100 Georgia Ave. NW.

* Dec. 4 in the 2500 block of 14th St. NW.

* Dec. 11 at 3800 Chesapeake St. NW.

From Dec. 10 to Jan. 9, a seasonal display in the conservatory called "A Sentimental Journey" will depict holiday images of 1948 and 1949, in a nod to the recently opened World War II Memorial.
