Sonja Keil provides insightful and empathetic glimpses into an alternative way of life: the caravan site on Bonameser Strasse in Frankfurt am Main, now known as the Bonameser Strasse community. She portrays the residents, highlights the historical background, and outlines the local political context. Through this group of people and their social fields, she makes an important contribution to social scientific milieu research. Keil focuses her social structural analysis on a specific group of people: they would most likely be referred to today as "mobile entrepreneurs." This includes showmen, circus members and their families, or those involved in the recycling trade. Their unique living situation is examined historically and empirically from an external perspective and is then complemented by an internal viewpoint. The perspective of this special group.
