If you want to enjoy a rib tickling look at railfans & steamnuts do a Google Search for
"Whistles in the Wind" by Graham Dukes. I ran across it by accident while looking for data on the Giesl Ejector.
By the way, if you are trying to post here and nothing happens run the courser over the title above and you can post. You may have to do it more that once during a posting, Don't ask me why
that works, I have no idea.
