The Way We Used to Do Things, Via John Cronin
John Cronin emailed me the link. He says a U.S. Attorney took it and then used it as evidence in the lawsuit that led to the closing and capping of the Croton Point landfill, on the Hudson River. When the case was over, the attorney gave John the film. You can read more about it on John's website, here.
By the way, I'm referring to John Cronin the former Hudson Riverkeeper, not John Cronin the Fish, which you may have read about here. I wonder if Terry Backer has a fish named after him?
