I was recently talking to a group of people about a random plot point in a video game, wherein a character reveals some coordinates written down on a sheet of paper and says something to the effect of "I think that's nearby, I will check it out." Nearly everyone in the group was thrown back by that, saying that there is no way that the character would know their coordinates off hand.

Later on, through entirely unrelated circumstances (some SciFi show where a human told aliens to drop him at specific coordinates), coordinates came up in a discussion with my family. Half of the family knew, half the family didn't know, and both halves were surprised by the other half.

I would be able to tell you if some random coordinate were within a reasonable drive of my city or not. I am curious about the ratio of people on Tildes that would know.

(I have absolutely no idea how to tag this)
