Cafe Citron celebrates 20 years with free salsa dancing lessons
Cafe Citron, a Dupont Circle bar and club, is celebrating 20 years in business as bars and restaurants around it seem to be dropping like flies. (R.I.P. Buffalo Billiards, James Hoban’s and Front Page.) A Brazilian samba show begins at 8 p.m., and at 9, you can learn how to salsa yourself. Don’t think you’ve got moves? There’s an open bar from 8 p.m. to 9 p.m. if you need some liquid courage.

Take a road trip to a National Park
On a few special days a year, the National Park Service waives the admission fees for national parks; Monday is the first of those days in 2020. Drive your own car, or use the money you save on admission to rent a ride and escape the city. Great Falls Park is only a 30-minute drive from the District, or venture a little farther to Shenandoah Park in Virginia, about 75 miles outside of D.C. If hiking isn’t your thing, the Colonial National Historic Park at Yorktown provides a trip back in time to colonial Jamestown,with guided tours and informational sites about the founding of the first permanent English settlement in 1607. End your three-day weekend with a return to nature or simply an interesting excursion outside of the hustle and bustle.
