Meridian Pint is advertising quite an appealing two-word offer: Free beer.

To celebrate D.C. Beer Week, the Columbia Heights eatery and Ashburn-based brewery Lost Rhino will give away free draft beer to the five people who find a person walking around the city in a rhino suit. According to a press release, the rhino will be hanging out in different D.C. neighborhoods this week. Its movements can be tracked using Meridian Pint’s Facebook and Twitter accounts.

If you find the rhino, snap a photo with him then post it to a social media site using the hashtag “IfoundtheRhino.” One photo will be selected from today until Friday. Those lucky five people get free beer that day and for the rest of the week at Meridian Pint.

Sure, this sounds like a lot of work. But just remember: Free beer.

Even if you don’t win, there are still plenty of ways to enjoy D.C. Beer Week. Check out DCist’s suggestions here.
