Abstract
Over the last 30 years, social theorists have increasingly emphasized the importance of space. However, in empirical research, the dialectical relationship between social interaction and the physical environment is still a largely neglected issue. Using the theory of structuration, I provide a concrete example of why and how space matters in the cultural analysis of an urban social world. I argue that bike messengers—individuals who deliver time-sensitive materials in downtown cores of major cities—cannot be understood outside an analysis of space. Specifically, I connect the cultural significance of messenger practices to the emplacement of those practices inside the urban environment.
