“It’s happening Saturday, in Adams Morgan. Join us for DC’s oldest (began in 1987!) and largest community yard sale: The Mother of All Yard Sales. This year, so far, we have 29 households participating! And after a two-year hiatus because of COVID, folks have lots of extra stuff to sell!
All of the homes are walking distance from each other, and Metro-accessible. Each sale begins at 9AM-ish and runs until that particular house gets bored.”
