Have you ever been present when some really important or monumental shit was going down?

You can judge yourself whether your story is big enough for this thread. I appreciate not everyone will have seen something as "good" as Kennedy getting shot, but reckon there's a few good tales in this thread. Let's not have a load of "had tickets for the basketball final of London 2012" please.

ie: I was in the room when Gordon Brown addressed Tooting Labour Party two days before their dramatic HOLD of the key marginal at the 2010 general election. Better than that please.
