The first 4 are public and other 2 are private.

In addition, there are 2 other good school in the area:

Peddie School (6 miles from Princeton)

The Hun School of Princeton

WWP North and South have much higher percentage of P admissions than other Ivies. This leads me to belive there are some home advantege besides legancy.

If Ivy is so important to you, maybe MA is better location since there are more pretigious colleges there.
