I was in 4th grade. I had bad asthma as a boy and I needed shots twice a week which required my mother and me to take a rural bus into Milwaukee. It made for a long journey but I got out of school for the morning. Anyway, my mom promised we would stop at Woolworth's and look at their pet turtles. We were looking at turtles when a sales lady told us the President had been shot. I'll never forget it.
