Every year, shoppers shake off their post-turkey sloth, drive to the malls to scrap over the best buys on the sales racks, stand in really long checkout lines, and get stalled in a traffic jam exiting the parking lot. Sound like fun? How about heading over to Internationalist Books for their celebration of Buy Nothing Day instead? Talk about easy activism: All you have to do is show up, listen to live music, munch on free food and watch the bicyclers in Critical Mass take over Franklin Street in the late afternoon. Not only is this much simpler than weighing yourself down with products you don't need, you'll be joining in solidarity with fasting consumers all over the world in pointing out Western culture's denial about overconsumption. Buy Nothing Day runs all day Nov. 24. Call 942-1740 for details.
