Brunch extending into afternoon with @davidlhawk #SystemsThinking discussion in back yard with wonderful weather. Mutual sensemaking on negotiated order applied to building 4-storey house without architectural drawings near Salina, Iowa. Steered discussion towards 40th anniversary of publication of Regulation of Environmental Deterioration, towards new chapter on It's Too Early, It's Too Late, Now What. Looking forward to some continuing the discussion when we might convene on a midwest road trip. (Riverside neighbourhood, Toronto, Ontario) 20190526
