No, ericcg, had honestly never heard of that. Not till you mentioned it did I google it up. Sure explains a lot. Was just mentioning a couple days ago to a guy on here how I learn things on here. Seems like years ago in the newspapers was a column by some nationally-known fellow who would every so often have a column on "things I learned in route to looking up other things". Guy's name was Sidney something-or-other, I think.
