I was in 8th grade in San Bernardino, Ca. I was walking out of gym class when I heard another student tell someone that the coach had just said that the President's been shot. I didn't think much about it until I got to my next class, when we were all taken to a larger room that could accommodate two or three classes so that we could listen to the live radio coverage. In those days, TVs in the classrooms were virtually unheard of.
As soon as it was announced that two priests said that JFK was dead, a girl, who happened to live down the street from me, ran out of the classroom sobbing hysterically. About an hour later, we were all sent home and subsequently got the following Monday off for the national day of mourning.
There were a few dunderheads at school who said that they were glad Kennedy died. What can you do?
When I got home, of course everyone was glued to the TV set. I went to my room and scanned the radio dial. Regular programming there was of course totally disrupted.
One of the area's rock and roll stations, KMEN, was playing somber funereal-type music, and was providing frequent news updates. One of the stations DJs from that time, Brian Lord, has this recollection of that day from his blog:

Last add: As a high school senior in Coronado, Ca. in June of 1968, I got to shake hands with Robert Kennedy the night before he was shot. I was on the ferryboat back to Coronado the next night when I heard the news on the car radio.
