“I can’t think of a better organization to support. Invasive weeds never seem to disappear, and it’s so difficult to get people to look at a pretty little flower and think ‘I want to pull it up.’ But, we keep on plugging away!” –  Stewardship Circle member Shelagh Broderson with Garber Park Stewards in Oakland.
