Putting Down Roots Sustainability Salons are an ongoing series of conversational salons in the French Enlightenment tradition: informal gatherings aimed at lively discussion around the notion of sustainability.  Some will feature one or more guests to lead a discussion or provide key insights on a particular topic, others will be open to whatever comes up.  Themes will likely include things like growing food (permaculture, local and urban agriculture, roof gardening, beekeeping, mushroom culture, etc.);  green building and green living;  urban trees, park exploration and stewardship;  regional air quality and watershed issues;  Marcellus shale, climate change, or alternative energy.  The afternoon discussions begin around 2pm at our home in Squirrel Hill, and are followed by a potluck dinner and a folksing.  Folks are welcome to attend for all or part of the afternoon and evening, and are encouraged to bring musical instruments as well as food or drink to share.
