The 42 best things to do in D.C. this weekend and next week

This week pitches the D.C. area fully into festival season, with Adams Morgan Day, outdoor jazz festivals in Silver Spring and Rosslyn, outdoor art shows in Bethesda and on Capitol Hill, a four-day celebration of singer-songwriters in Annapolis, the Small Press Expo for lovers of comics and graphic novels, and the first stirrings of Oktoberfest at local breweries. Art All Night, which the District says drew more than 250,000 participants last year, returns for two nights of parties in all eight wards of the city, bringing live music, murals, DJs and pop-up fun. One of D.C.’s most adorable residents turns 5 with special treats on Saturday morning, while cyclists of all ages take to the city’s closed streets.
