The poet Marianne Moore famously wrote of 'real toads in imaginary gardens,' and the labyrinth offers us the possibility of being real creatures in symbolic space...In such spaces as the labyrinth we cross over [between real and imaginary spaces]; we are really travelling, even if the destination is only symbolic.

Cities have always offered anonymity, variety, and conjunction, qualities best basked in by walking: one does not have to go into the bakery or the fortune-teller's, only to know that one might.

Las Vegas suggests that the thirst for places, for cities and gardens and wilderness, is unslaked, that people will still seek out the experience of wandering about in the open air to examine the architecture, the spectacles, and the stuff for sale, will still hanker after surprises and strangers.
