I think that for me, it's about triangulation of different things. And I wonder if maybe in efforts to scale up if there could be some strategic and creative triangulation of different modes of evaluation and measurement, so that on some level, I think that it's hard to measure community impact. And I think that, like you said Sarah, what were the values that you set for yourself in doing this project? And if those values were I'm going to do no harm while I'm here, I want to leave something that they can hold onto afterwards and I'm going to follow up with them to extend the relationship beyond this one event. And those are the core values then I think that you can build something around that. I think that it's tough to grapple with scale when I think that so many of these things are so specific to a certain geography, to certain histories
