With over 2,800 units full of people and their stuff (and precious little closet space), the sheer amount of clothes, household goods, books and art accumulated by Penn South residents is staggering. But what to do with it all? For the past 28 years, their annual rain or shine open-air sale has proven that one person’s beloved (but disposable) property is another person’s reasonably priced treasure. The 29th Annual Penn South Flea Market fills the stretch of West 26th Street (between Eighth and Ninth Avenues) with 200 tables featuring the wares of area residents. In addition to the aforementioned booty, vendors will be offering handmade crafts — including pottery made at the Penn South Ceramics Studio. Happening from 10am-4:30pm on Saturday, June 1, the event raises funds for the Penn South Parents Committee (which runs free sports programs, dance classes and other activities and events for youth living at Penn South).
