Agents of celebration for FBI centennial

— -- The FBI turns 100 today, and though the agency isn't inviting the public in for cake (its popular tours ended due to post-9/11 security concerns), one Washington attraction is commemorating the milestone with a new exhibit.

G-Men and Journalists: Top News Stories of the FBI's First Century at the Newseum showcases 200 crime-related artifacts, including the Unabomber's cabin, John Dillinger's death mask and Patty Hearst's coat and gun, along with hundreds of photographs. (Admission: $20 adult, $13 children; 888-639-7386; newseum.org.) The new Liaison Capitol Hill hotel in Washington is celebrating with a two-night G-MANia package through Sept. 2 that includes tickets to the Newseum and a $50 food credit, starting at $179 a night weekends (866-233-4642; affinia.com).
