You Have A Time Machine To Go Back For One Day, Where Do You Go?

I actually think about this question more than I probably should. If I had a time machine and could go back for one day, what day would I choose. I know a lot of people would choose the day Jesus was born. But that's too iffy for me. There's no guarantee the one day you pick is the right day.

So I try to pick a day when we for sure know something happened. And I struggle between a few, but I think there's one that stands out above the rest. Oh, and you can also go to anywhere on the planet, not just where you are now. Here are a few of the days that I might want to go to:

• 7/13/1985 - I would be at Live Aid watching Queen perform. There are also other bands that I would like to go back and see, like Led Zeppelin, but if I have to pick one concert, it's this Queen show.
• 5/25/1977 - I know it would probably be more exciting to see Empire Strikes Back than the original Star Wars release date because the crowds would be bigger and if you really wanna be a dick, you can yell out "Vader is Luke's father!" right before they announce it. But I should also mention, that the point of going back is to just witness an event or see something, not change the space time continuum. Which leads me to the next event.
• 6/6/1941 - Yup, D Day. This one obviously scares me. Hell, just the intro to Saving Private Ryan scares me. But if there was a way to be in the time machine and see just how huge this was, it would be worth it.
• 11/19/1863 - The day Lincoln gives the Gettysburg Address. Not only is it a historic event, but I could also hear if Lincoln's voice really was high pitched.

There are a lot of other days I'd go back to, but here is the one I would, just to witness what really happened:

• 11/22/1963 - And I would damn sure would be at Dealey Plaza in Dallas. Remember, you can't change anything, you're just witnessing the event. Of course I would take with me, and set up tons of cameras so I had footage of everything. But that is the one day I would go back to just to witness an event.
