What happens when one moves about in the city? In this essay I will explore how we through our movements create our own temporal cities. I base my investigation on Michel de Certeau's theories from his book The Practice of Everyday Life vol 1. De Certeau believes that by just walking in the city ? a mostly unconscious and for many trivial activity ? you write it, creating different types of spaces that can be understood using linguistic terms.In my essay, I develop de Certeau's theories about ordinary activities by applying them to two less ordinary ? and between themselves quite different ? spatial practices:  fare evasion on public transportation (Plankning) and the urban activity of parkour.
