I was in third grade at H.B. Davis School in Pittsburgh. The teachers decided not to tell us anything and we finished the day at 3:30 EST as usual. I got home just in time to hear on TV that the president had died. I recorded the audio that night of LBJ's speech at the airport and watched the rest of the weekend. We were at my grandfather's when Oswald was shot and I was at a friend's during the actual funeral.
I still have the newspapers from that weekend.
Kennedy's assassination was before my time (I turn 30 on Fri) but I do want to chime in with a memory of mine from high school. It was my (I think) sophmore or junior year in HS when we studied it, and the history books at the time just didn't have much information on what happened. I told Mom this and she said, "Wait a minute" She goes to the hallway closet and pulls out this stack of newspapers that had to be damn near a foot thick, from the assassination itself to the funeral. She also had a book entitled Four Days: The Historical Record of the Death of President Kennedy'. Thanks to Mom, our class had a treasure trove of information on this subject.
