We’re no strangers to celebrity sightings in the District. We don’t bat an eye when we see Barack and Joe scarfing down half smokes at Ben’s. The Big Papa in his Fiat? That’s nice. Ovie out and about? Yawn. Yeah, none of those celebs have anything on Bei Bei, the giant panda cub who makes his public debut on Saturday at the National Zoo. Grab your camera and get down to Woodley Park, though you might have better luck getting interesting shots of the crowd than actually seeing Bei Bei. There are also plenty of events around town to commemorate Martin Luther King Jr. Day. Remember to tag your MLK weekend photos #DCFocused on Instagram. We’ll have a roundup on Tuesday.
