"Seeing maps as places where secrets are burried, changes the use of them.

Traversing every street is not generally a feasible goal but getting lost by calculation with a map can serve some of the same purposes.

If in our notion of urban space its most interesting bits are not easy to get to or fully displayed, if we see a city as a puzzle or a set of riddles, we will believe ourselves closer to its heart when lost or going nowhere in particular."
