Hey, Bill ! I hadn't thought of that classic OLDTOOLS post in years!  IIRC, it's
got to be a caterpillar-tracked steam tractor with a brass whistle.
 
Oh, I suppose the newer members of the list would like a pointer to the story,
but I can't find one.
 
There was an almost universal gut reaction that that's what would happen to each
and every one of us if we ever tried to bid on something like that with SWMBO
present!
