The region between Baton Rouge and New Orleans, Louisiana, is known to some as “Cancer Alley.” Environmental justice activists provide “toxic tours” through this area to address how racism and classism have created an environmentally unjust climate. Drawing on participant-observation to critically represent one such tour, the author illustrates how toxic tours may function rhetorically as cultural performances to help build communities of resistance through acts of politicizing memory. Examining how chartered buses, tour guides, and “stops” rearticulate what and who should be preserved, the author argues that the tour both enacts what Dean MacCannell calls the tourist practice of “sight sacralization” and contests conventional tourist representations.
