Readers: At times, rather than recalling a specific event, we peek at a day in the past, usually a holiday. Today we mark Thanksgiving, 75 years ago, on Nov. 26, 1942. America — and, up front and personal, South Florida — had been in World War II for less than a year, and much had not gone well. On the plus side, with wartime employment, people had money. But it wasn’t easy to spend; rationing and shortages were the rule. Through it all, Palm Beach County and America remained thankful.
