This week's RF Cafe crossword puzzle contains the usual assortment of engineering and science related
words and clues, but there are also a few specific words commemorating our
Thanksgiving
Day holiday (indicated by a asterisk
*) that is celebrated each year
on the fourth Thursday of November. Macy's
90th Thanksgiving Day Parade occurs on the morning of November 24th and follows a route along Central
Park West and 6th Avenue. Interestingly, the parade was
cancelled during the World
War II years of 1942, 1943, and 1944 in order to conserve much needed raw materials.

Take a well-deserved break and try your hand at some of these goodies.
Every word in the RF Cafe crossword puzzles is specifically related to engineering,
mathematics, and science. There are no generic backfill words like many other puzzles
give you, so you'll never see a clue asking for the name of a movie star or a mountain
on the Russia-China border.
All of these crossword puzzles were created using the fabulous
Crossword Express (now called "Magnum Opus") software.
