Today's libraries are not just for books, computers and magazines – the Salem Church library now has its own geocache!  In geocaching, participants obtain the location of a geocache from a geocaching Web site www.geocaching.com, use a GPS to arrive in the area of the cache, and then follow clues or simply hunt for the cache.   There are over 1000 caches waiting to be found within a 25 mile radius of the Fredericksburg area!

She’s only four feet tall and 110 pounds, but little “Ardi” is causing a sensation among paleoanthropologists. Earlier this month, after fifteen years of research, scientists reported that they had identified Ardi’s skeleton as the oldest hominid known to modern humans. Ardipithecus ramidus, as she is formally known, lived 4.4 million years ago in what is now Ethiopia. She’s remarkable not just for her age, but for what she tells us about human evolution. Scientists are re-arranging the human family tree in light of this new research.

"That's one small step for [a] man, one giant leap for mankind."

Born August 5, 1930, Neil Armstrong has been an aviator, test pilot, and university professor. And, on July 21, 1969, he became the first man to walk on the moon. In the days before the Internet or cable television, people around the world gathered around their sets to watch history being made.
