Here is some infomation to keep depending on what you're writing about. Not techinical, just something that interested me. I bought a book at Wordstock in Oct based on the PA mine fires. I haven't got to it as I'm reading a story about the Tillamook burn in '52.... The year caught my eye. Its my birth year so I had to buy it. So far so good.
