Current issue of THE ARTILLERYMAN has an article on the deteriorating bronze cannons at the Washington Navy Yard, with some "before" and "after" photos, how people had written letters which remain unanswered, etc. etc.
As you know I've been interested in this so I will have to contact the publisher to get a copy, my subscription lapsed back when.
But it isn't like I know nothing about it, THE ARTILLERYMAN did interview me in the course of preparing their article.
This Navy Yard thing is a long-term project, but I can guarantee we'll get results eventually. It is just a matter of getting the right people in Congress interested as they are the only ones who have a stick big enough to beat the Navy into submission on this.
