Inaugural weekend is here, and we’ll help you find the Post’s best coverage of the balls and parties and nightlife. You’ll be able to follow some of the nightlife action tonight and Sunday on the Post’s own Inauguration Grid.

Tonight, you can follow Dan Zak and Monica Hesse as they compete in their own inauguration version of “The Amazing Race”: A race to see who can make it to more inaugural balls in just under four and a half hours. They’re calling it The Running of the Balls, of course, and there’s a rigorous system of rules: They can’t leave one ball for the next until they take “a photo with a food item or beverage whose name is a political pun” or if “a song by Stevie Wonder is played in part or total” or several other potential conditions are met. Their very exciting story of the night will appear on Monday, or you can follow them live on Twitter, @mrdanzak and @monicahesse.

Meanwhile, enjoy this delightful flashback to 2009: Four years ago, a millionaire threw an inaugural ball for homeless people, disabled people, wounded vets and the otherwise down-and-out — “the who’s who of the everyday world,” as one guest remembered it. DeNeen Brown catches up with some of those people and finds out one magical night had lasting effects for some.
