Covered Bridge of the Day

Shown below, are two photos of another WV covered bridge. It is the 43 ft. long Center Point covered bridge built in 1888. It uses a variant of the multiple kingpost truss, which has what are called counter braces. (The diagonal members opposite of the braces, which are the primary compression members of the truss.) It spans Pike Fork, McElroy Creek on old WV-23 in Center Point, WV. It was rehabbed in 2002.





Is the American government in charge of cruise ships and mountain climbing ?


The Editor:  Are diamonds forever, LL ?

Cubic Zirconia  Cat:  No.  They do last a long time.  Here is something that might come in first.  This stuff can change genes/DNA quicker than a bio-genetics company.

Here is another change that will rank up there with tobacco won’t hurt you, Agent Orange and Roundup are safe, and plastic won’t leach poison.

In a few years these frankenfish will be loose, in the ocean,  and eating sharks.  They are as safe as the first article in this issue.

Be careful at the airport.

Astronomy Picture of the Day

Stephan’s Quintet from Hubble

Explanation: When did these big galaxies first begin to dance? Really only four of the five of Stephan’s Quintet are locked in a cosmic tango of repeated close encounters taking place some 300 million light-years away. The odd galaxy out is easy to spot in this recently reprocessed image by the Hubble Space Telescope — the interacting galaxies, NGC 7319, 7318B, 7318A, and 7317 (left to right), have a more dominant yellowish cast. They also tend to have distorted loops and tails, grown under the influence of disruptive gravitational tides. The mostly bluish galaxy, large NGC 7320 on the lower left, is in the foreground at about 40 million light-years distant, and so is not part of the interacting group. Data and modeling indicate that NGC 7318B is a relatively new intruder. A recently-discovered halo of old red stars surrounding Stephan’s Quintet indicate that at least some of these galaxies started tangling over a billion years. Stephan’s Quintet is visible with a moderate sized-telescope toward the constellation of Winged Horse (Pegasus).
