It's time to sharpen your pencils, cudgel your brains, and consult your muse: NCSE is running a bumper sticker contest! This is your chance to speak loud, speak proud for evolution, by crafting a killer slogan that could end up on the tail end of thousands of cars. The aim of this mobile message: to spread the good word about evolution and evolution education. Your bumper sticker can be funny, profound, fierce — whatever, as long as it's good. Full details of the contest, and a list of the fabulous prizes on offer, are available on NCSE's website. The contest ends on September 5, 2011.
