170 students from across the southeast are spending their summer vacation helping Oxford and Anniston residents who are in need. The World Changers organization is a nationwide Christian charity that has volunteers help residents with various home projects, such as painting houses, repairing roofs, and many other chores. One student is happy to give back after others helped him. With more than 10,000 teen and adult volunteers nationwide, event organizer Hannah Wells is pleased with the turnout of young volunteers. World Changers has 14 crews working at 17 sites in Oxford and Anniston this week.
