“If all goes as planned, and that is no sure bet, an unlikely crew on an improbable craft will amble the Mississippi for the next month, spreading culture and chaos downriver. For more than a week, the ‘Miss Rockaway Armada’ — a few dozen self-selected artists from Manhattan, Brooklyn, Seattle, San Francisco and beyond — has toiled … on the banks of the Mississippi River, assembling salvage wood and cadged Styrofoam into three interconnected rafts, each 20 feet long. … Theoretically, the crew plans to stop in various river towns to give workshops on everything from silkscreening to power tools and put on a performance — a kind of punk-rock musical variety show — followed by a dance party.”
