If you add all eight schools without Hawaii, then the midpoint is south of Frazier Park, CA.
This is west of Gorman off of I-5.
The center of minimum distance is in 2650 Benedict St Los Angeles, CA 90039, USA.
If you add San Diego and Bakersfield, then the midpoint is in the Los Padres National Forest west of I-5.
The center of minimum distance is 2610 Onyx Dr Los Angeles, CA 90032, USA.
Edit: Playing "weight by time" by how long you lived in each place is kinda fun.
