Vehicles for Exploration

It is very interesting how the authors of the three pieces for this week use simple issues such as park use and bus ridership to express more complex and important aspects such as class struggles, racism, gentrification, planning, and the right to the city. I wonder what other vehicles can be used to successfully portray similar or other urban and socio-economic issues. Can we, for example, look at the history and development of restaurants on our Crown Street to describe dynamic demographics and socio-economic changes in New Haven? Other vehicles may be nightclubs or parking garages..
