I remember Elvis dying, as my Mom cried and cried. It was later, but I distinctly remember John Lennon dying, as my parents were out of town and we had a babysitter who was in high school at the time and she cried and cried and cried. She was like totally forgetting to feed us so my brothers and I called her mom, who came and stayed at our house until the babysitter calmed down a bit. I remember the gas shortages too, long lines for the pump and $0.50 a gallon, the horrors. The Shaw of Iran and the Ayatollah, hostages, the whole ball of wax.
Actually, probably the earlier somewhat newsey thing I remember was the Bicentennial in 1976 (I was 5) as all the men in town grew weird beards and ran around in old clothing (women and men, and unsuspecting kids). They put up patriotic bunting all over town, made these "shields" with the picture and info about each US president and placed them on the lampposts all down main street, and gave my silly little hometown of 2,000 people the official nickname "the city of Presidents" even though no real US president has ever even been there. They repainted the watertower from black and gold (the school colors) to red, white and blue and have kept it that way ever since. It was a little odd, so I'm sure most all kids from there who were my age or older remember the summer that the town turned red, white and blue.
