A young man was sitting in his home in Great Britain , surfing the Internet, looking for medical mission trips. He discovered one and now has 5,128 frequent flier miles when he arrived in Sioux City recently. Actually, he has many more than that after accompanying a Sioux City evangelical and outreach mission on two trips outside the United States. Just before Christmas, Phil Hall, 19, of Birmingham , England , \"Googled\" the words \"Christian medical missions\" and found Light of the World Missions and Outreach Ministries, a missionary group based in Sioux City . The adventurous side of Hall was intrigued with Light of the World and that feeling was returned by Bobbie Nutt, president and director of the group. Currently, Hall, Nutt and medical students from Wayne State University , Detroit , Mich. , are doing mission work in the Mayan villages of Belize . They will be gone from March 3-11.
