On Monday, July 28, SDS, backed by activsts from both Potomac Earth First and Roadblock Earth First, staged the "Funk I-69" protest, treating the CATO institute, an office of I-69's surveyor, and the dual target(I-69 and ICC) Washington Post they way SDS normally treats military recruiters. The first target on the menu was the neoliberal Cato Institue, one of the thinktanks responsable for NAFTA. I-69 is being built as one of several "NAFTA superhighways." The glass-enclosed lobby of CATO was stormed by protesters before the cops were able to respond, sparking a pushing and shoving match, but no injuries.
