Quantum Leaping

Another "getting to know you", self-devised, based upon past ruminations over an old favorite TV show, "Quantum Leap", and over the possibilities in myriad novels based in the past or based upon time-traveling.

If you could go back to any place, any "when", in time, where and when would go, and why? One caveat is that you cannot go back to change something -- you can't save John Lennon from being shot, or save a friend/family member from getting killed in a car crash, etc. You can just go back to observe, to witness (though you can interact with people and things in the past). Maximum of five choices.

Think about it for a while. When you've made your choices, post some of them here. Ask you friends/family what their choices would be. The differences in the selections can sometimes be illuminating. I'll post mine in a couple days, so I don't predjudice your thoughts on this.
