I have pursued two organizations:
Sorority #1: was one which has a chapter at my undergrad university. I was really excited whey gave me a bid about 4 hours after informal recruitment started. (!!!) Unfortunately, I wasn't able to accept it due to the worsening of my mother's illness. Three years later I did informal with this group again and it was an awful experience. Sometime later, I decided to give it one last go with AI. I had an OK time with the alumnae members, but the memories of my negative experience with certain collegiate members kept me from truly feeling like I could be at home there.
Sorority #2: I found by chance. They do not have a chapter of their organization at my undergradute university. However, there is a chapter about an hour away.
