Pick a good or bad one!

I'm stealing this one from you Carl (-:
1955 – American Civil Rights Movement: In Montgomery, Alabama, seamstress Rosa Parks refuses to give up her bus seat to a white man and is arrested for violating the city's racial segregation laws, an incident which leads to that city's bus boycott.
1969 – Vietnam War: The first draft lottery in the United States is held since World War II.
Somewhat misleading, since I was drafted into the Marine Corp during the Korean War.
I don't know if it's a character flaw or not, but I seem to select events that are personal in nature.
