I joined Twitter a while back, and lots of people tweet about what they're thinking, who they're with, what they're doing, and where they are. I've noticed in the "where" tweets, that humans, even with all these maps, navigation technology, general technology, and hell, language, still refer to places by natural landmarks and topography. Every city seems to have a "hill" that they're on, or people mention what mountain they're facing, what valley they're in. It's nice to know that deep down inside, we're still cavemen navigating locally by the land, and that we connect to it by communicating our location to others. It feels both instinctual and tribal.
I'm here, on this landmark. When I'm gone, this landmark will still be here. And somebody will be standing there, announcing his presence to somebody in our community. They will hear him, and they will know where he is by sight, or by memory. They'll be able to feel the strength that it takes to climb a hill in their legs, or remember the feeling of wind through their garments as they enter a valley. They might hear the lapping of a lake and know the curve of the shoreline: it reminds them of the line of a woman's body, as she walks away. They'll know in their minds and their bodies exactly where he is.
Or they'll look it up on Google Maps.
Rule: Be a caveman sometimes. Memorize places with your body.
