Celebrate the beginning of warm summer nights (well, hopefully) with an outdoor screening of Lost Rivers. Presented by the Homegrown National Park Project, the documentary examines waterways that flow, unseen, beneath our cities. Why is this any better than the other outdoor screenings around town? They’ll have food trucks, a campfire, and marshmallows for toasting! Bring your own blankets or small folding chairs.
