ABSTRACT
This chapter examines the urban life of Mexico City in terms of spatial experiences that occur during the mobility of everyday life and the singularities acquired by the navigation of popular urban areas. The dense fragments of urban life under analysis may pertain to Mexico City but, despite their singularity, they have links with phenomena found in other cities. Liminal spaces can be considered micro-territories or islets that become gateways to places different from the setting in which they originated. The chapter focuses on circulatory spaces in Mexico City and, more particularly on liminal spaces that have been created within the public Metro system for the sexual practice known as cruising. In Mexico City, the indoors of public transport usually presents a high density of occupation, which restricts views of the neighbourhoods and streets on the route outside, or at the very least fragments them into discontinuous images.
