Christmastime is upon us once again, and amazingly another year is coming to an end. This
marks my 58th Christmas here on Earth - that's 58 trips around the sun and a barely measurable
distance around the Milky Way galaxy; where has the time gone? "Tempus fugit," as the dial
of my
grandmother clock proclaims. In fine tradition, this week's engineering
crossword puzzle has a special theme that contains a heart-felt message from all the staff
(Melanie and me) here at RF Cafe. We hope you had a good 2016
and that you will have a safe and happy holiday season. Carpe diem.
