tommac, I note that you're a chemical engineer. I hope you're not anything like a chemical engineering graduate student I once encountered at Ohio State University. Immediately after the MacArthur firing by President Truman, this graduate student wrote a letter on toilet paper, saying, "This is what I think of you", sealed it into an envelope, addressed it to President Truman, placed his own return address on it, and mailed it. He wrote a second letter at the same time in which he said, "If you ever come through Columbus, Ohio, you can depend on me to blow your head off with a high-powered rifle". Both letters were intercepted at the post office in Columbus, Ohio, and turned over to the FBI. I was told by the occupants of the apartment in which he was renting a room in the same apartment building my wife and I were living in, that seven cigar-smoking FBI agents showed up and arrested him. He spent a month in jail while the investigation went on. He was eventually released as a "harmless nut". He dropped out of the university.

Are all chemical engineers like that? I wouldn't know since I'm a physicist!
