IMO, nothing to apologize for, there!

We're supposed to be Collaborating! And, like good science, the more researchers who independently come to the same conclusion -- the stronger the theory!
That's why I'll pick up a crumb, and chase it as far as I can -- before I come back here to see what others are saying... So what -- if I've duplicated effort...
Thank you, TXnMA. That is a good point about collaboration and independent corroboration. Sometimes I feel silly coming to a conclusion and announcing it, then I read the thread to catch up and it’s like “where were you TEXOKIE? We decided that a long time ago!” LOL! but you are correct. Let the plodders plod and the sod will be more solid!
