Urban strolls allow to intercept the atmospheres of a space, mediating between the moving body and the context. With a situationist approach, I carried out an exploration of the sprawlscape along the SS554, the urban motorway connecting Cagliari (Italy) and its surrounding centers. The contexts I met, a particular fusion of rural and urban, are considered marginal and degraded compared to the city, thus the choice of exploring on foot, driven by the difficulty that these spaces pose to walking and the possibilities it allows to explore spaces atmospherically. The stroll was integrated by a photoreport called « flatshades » : photography is a useful medium to explore and interprete the atmosphere of a space, and it allows the (re)presentation and sharing of this personal perceived atmosphere.
