Mayor Anthony A. Williams’ bid to get the public to pick up its pens has borne early fruit. In the 3500 block of Connecticut Avenue NW, someone has joined forces with the mayor: In the white space of a Williams campaign sign, there now is a room-for-let ad. “ANTHONY rent call 202-5371062 DEMOCRAT” it reads across the middle. Going up and down: “$585.00 a month WRITE-IN…WILLIAMS.” —Joe Dempsey
