First, the Yawkey Center for Cancer Care construction site, made into a thing of wonder by the ironworkers' spray-painted tribute to the children getting treatment across the street at the Dana-Farber Cancer Institute. There were children's names posted on the Farber's windows the morning I was there, but I wasn't lucky enough see workers with cans of paint.
I can't do justice to how extraordinary it is to see this in person. I'll just say that it feels more powerful than anything I've ever experienced in a church. The Boston Globe had an excellent feature about it last month.
