Alright wise guys, here it is. Since you all have been saying how easy the last two weeks' challenges were, you get no hints this time. None! And because I'm feeling spiteful, you don't even get any color in the chart.
You know the deal - identify the data below. Write the answer in the cover letter of your application to be the new Secret Service director and convey it, by hand, over the White House security fence and as far across the North Lawn as you can get, handing it over to the first agent who tackles you, and kindly request that they forward it to me, c/o The Washington Post.
Or just tweet me, email me, or leave a comment.
