I thought I would dive in to this thread. But as usual, I am more confused with the answers than I am the questions. Did I miss reading an explanation somewhere in this long thread?
From the first post "It's perfectly OK to post cryptic answers.", meaning the answer should indicate to the puzzle poster that the answer is known, without spoiling it for others.
So, my answer is 6,288, and I think Salty has it, though he has a geographical advantage.
Another guideline should be: After at least one player (or maybe two) has properly identified the location and the "what happened" part to the author's satisfaction, it would be very kind of y'all to post a fuller explanation and description so that those of us with more obtuse abilities might be enlightened.
