In California, there seem to be few, or no chapters of the following:
AGD
ASA
Phi Mu
DZ
ASA
Phi Sig
AOII
ZTA
KD
SSS

, especially for KD, since I'm a legacy!
There might be more sororities that aren't very prevalent in CA, but I can't think of them right now.
On the other hand, there seem to be many (or more than a few) chapters in Cali of the following:
Theta
Kappa
Pi Phi
Chi O
DG
Tri-Delt
A-Phi
ADII
Gamma Phi
Sigma Kappa
Alpha Chi
Can you tell that I'm procrastinating from writing an essay?
