Several Directors from the Think Tank that has yet to be named (including me) converged in Boston a couple weekends ago to present a project called “Community” in Question: Conversations and readings on art, activism, and community vis-à-vis the Green Line Expansion in which we investigated the proposed public transportation expansion (MBTA Green Line) into Somerville-Medford to examine how residents respond to (both for and against) changes in transportation and how transportation effects their cities. The project was developed for a conference on the intersection of art and activism at Tufts University, and, while the conference proceedings I attended were rather exasperating, I think our project was one of the TT’s most successful to date. We organized a talking/walking tour along a portion of the proposed transit expansion Somerville and then culminated at the Davis Square T stop on the Red Line in Somerville’s largely gentrified central hub. The unique opportunity here was to observe and discuss the effects of the previous expansion (dating from the mid-80s) on the community 25 years hence in order to consider the potential effects of Green Line expansion on another part of Somerville and adjacent Medford. In the process of developing the project we contacted and invited key stakeholders and policy makers from the community to offer their expertise and perspectives, and several of these folks joined our walk and greatly enriched the conversation. Also noteworthy is the release of Vol. IV in the series of occassional readers which compiles several texts on the following themes related to the question of community: Theoretical discussions on Community, Learning from Activists/Organizers: How to participate in a community, [Common] Space, Artistic responses to Community, Building Communities.
