By guest blogger Joan Morrison:Once again, our majors have been called upon to conduct some serious testing of waters in China, Cambodia, and Laos, on the summer study abroad program “River Cities of Asia.”  Well, not called upon by the governments (not yet anyway!) but by professors leading our trip.  Renee, Sakile, Rose and Shaina can show you how it’s done and even look like they’re having fun testing the muddy Mekong!
