If your memory serves you well...
I have a couple vivid '68 memories (I was 10):
1. Waking up to find note from my dad on kitchen table he had left before leaving early for work. It said that Bobby Kennedy had been shot late last night. I recall discussing that with kids at school. We were certainly aware of MLK, Vietnam, riots in urban cities and on college campuses. Losing our childhood innocence.
2. RFK's funeral train passing thru our town.
3. My dad taking me to see Democratic Prez candidate Eugene McCarthy give speech outside hotel in my NJ town.
4. Riots in nearby Newark, NJ brought the craziness uncomfortably close to our lil' suburban town.
5. Apollo 8 circling the moon Christmas '68
6. Beatles, Motown, and bubble-gum hits on top-40 AM radio!
