Thanks for the recognition of my original query about the special concrete ties shown in the cover photo (I agree that it was only available on the paper edition).

"Next time", I'll wait until the discussion about an article is complete before asking a specific technical question. And I'll compare the electronic edition graphics to the paper edition graphics.

Yes, I am ancient; I read a general-interest paper newspaper, seven mornings a week. I read Larry's fine newsline the previous evening, thanks to our time zone difference - or whenever I wake up during the night. (You may learn about "that" later) His report is based upon what the next morning's paper newspapers plan to carry. If I find something that his GOOGLE searches missed, or something that "broke" later, I'll forward a lead for him to consider for the following evening's edition. I believe that he has never failed to find my offerings. Pleased to note that others are doing likewise.

Thanks Dave. Thanks Larry.
