The 30 best things to do in D.C. this weekend and next week

The National Cherry Blossom Festival and March Madness get underway this weekend, but there’s much more to do than watching basketball and awaiting the arrival of flowering trees. There are art galleries to tour in Georgetown, and the return of the D.C. Environmental Film Festival and the Polish Film Festival. Chess players of all skill levels can find a game at an Adams Morgan bar, crafters can meet in a historic backyard beer garden, and one of D.C.’s best dance parties returns to an unassuming loading dock. Marvel at a trio of larger-than-life bison on the National Mall, and don’t forget to book a ticket to see the new elephant calf at the National Zoo.
