I know that I enjoy the intellectual exercise. Of course, you all don't read about the cases where I've been wrong and wasted time researching one of the points that I couldn't establish as wrong. (I still have my doubts about the world's highest double track rail bridge. I did establish that their claimed record was for height above the water, not height above sea level, but I haven't come up with a better contender yet.)
I appreciate all your efforts even though the thought of all the work you must go through makes my head hurt sometimes!
