Take a look at the DeKalb County High School and Middle School Attendance map. Let me know if you see anything funny about the Cross Keys and Sequoyah districts compared to Chamblee, Dunwoody, or Tucker.
When you find Cross Keys High School, take a look at how close it is to the Chamblee High School district border. Now I ask . . . where SHOULD those kids go to school and where DO they go to school?
