This chapter is a study of bottom-up mobile food trucks in Charlotte, NC over three months in 2015. This chapter is the first of three case studies that address urban commerce driven by social media at the neighborhood level. The ability of the food truck vendors to mobilize and change locations temporarily and to schedule and announce their intentions on social media are salient features of this chapter. The chapter illustrates a detailed analysis of the nature of the site analysis and the arrangement of the truck, as well as interviews with owners that provide a detailed picture of the web of the local community, urban space, and social media. Data analyses of vendors’ tweets include K-means clustering and sparkline mapping.
