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.
