Absolutely no other girls from my HS are DG's.
The "popular" sororities in my hometown area include Zeta (every campus near me has a ZTA chapter), Tri-Delt, ADPi, and Phi Mu (those are just the ones I can think of off the top of my head). That's part of the reason I want more Georgia DG chapters! I love my sisterhood and I want to share the love!
