Here's an article from The Princeton Packet on the book and an upcoming reading at Stony Brook-Millstone Watershed, Thursday June 26, 7:30.
One thing about the article: I don't know for sure if fewer kids are swimming in the river as I don't live there anymore. I was mainly commenting to the reporter (and in the essay "Swimming Holes") about the differences between that Delaware culture and the one I experience at home on the New, but perhaps both have changed some. Fewer swimmers in both places.
Since this came out near my hometown, I heard from an old teacher: "It's always fun for me to answer the retired educator question, 'What ever happen to ...?' Another mystery solved!"
