Hey, Metman, sometimes a little levity is good for us old stuffy engineers. After all train driving gets sort of boring after a while. I, too, hope my remarks were taken in that vein. They were intended as such.
I iterate again, back to the subject of the thread, that I would be interested in such a forum that addresses intrests that I have.
And, if you are ever in the Las Vegas area, do the Hoover Dam tour. To bad security considerations no longer permit the "hard hat" tour that took interested parties much deeper into the belly of the beast, (for an additional fee, of course). Very interesting for an old boiler guy more oriented to thinking in terms like supercritical, deep vacuum, etc.
