Thank you ! You've reminded me of a neighborhood ritual from my stay in major Pacific Northwest urban setting. On Saturday Night one of the parking lots between two commercial structures was vacated and a couple of well advertised classic family films were projected on the white wall of one of the adjacent buildings. All attendees were encouraged to bring their own seating and negotiate the space with their neighbors. There were basic ground rules to maintain civility, but the free form approach was very inspiring and felt very familial. This is akin to the rituals of Tailgate Parties at NFL Stadiums and the like. The variety of seating like couches, folding and even just blankets lent a homey sprit to the encounter.
