Thanks for the kind words Bret and Jim! I really appreciate them.
A long term idea that I've had is to compile the different articles that I've written (and will write) into a book eventually. This would include most of the Sumpter Valley engines that were still on the line in the '30's and 40's, as well as all the OLC engines. As Bret said, it is hard to say when to call an article done, because new Sumpter Valley stuff just keeps popping up all the time. That's one thing I love about the Sumpter Valley fraternity: Along with being dedicated railroaders, they are also historians and sleuths.
One thing that everyone can be guaranteed is that the future will undoubtedly reveal some really spectacular artifacts and information having to due with the Sumpter Valley. Stay tuned!
