CaptionOutside their house, Mennonite Herman Fehr, his wife and three daughters are almost blown off their feet by the strong wind. Mennonites are a protestant group descended from the 16th-century Anabaptists. They oppose military service, favor plain dress and believe that schooling threatens their way of life. In the 1920s, groups of Mennonites emigrated from Canada to Mexico to escape government interference. In most Mexican colonies jewelry, watches and recorded music are banned, and it is forbidden to drive or own a vehicle. Today some 50,000 of Mennonites still live in northern Mexico, but thousands have moved back north because of the harsh conditions.
