I had to think, but I can narrow it down to either Delta Gamma or Alpha Phi.
Delta Gamma - I liked Anchor Splash, ships and Raggedy Ann/Andy dolls (childhood memories). I think that any philanthrophy concerned with the blind such as theirs is truly worthwhile. I like pink and blue. Also, their letters DG correspond to the motto - Do Good. Mainly, though, I just like the personalities of the girls/members that I have met through the years. Recently I met a Mizzou DG undergrad who was really fun and impressed me. She reminded me of my DG friends.
Alpha Phi - my best friend and a second cousin were Alpha Phi's. Also, Lady Bird Johnson turned down an Alpha Phi bid because her family did not want her to be Greek (I read this in a book on her). These girls have such courage and grace, and I like the symbols- the bear, the ivy, and two beautiful flowers- the forget-me-not and the lily of the valley. They remind me of Spring, my favorite time of the year. Also, their national headquarters is in Evanston, a close Chicago suburb.
But my love is with my own Pi Beta Phi.
