Roxy--
I'm so sorry you are deciding to drop out of recruitment now. I understand that from your first impression you may not be really into AGD and ADPi, but I would, like dzsagirl, encourage you to go to their parties and see what it's like. I know that someone on here posted during the Fall about going through recruitment and only getting invited back to one house. They figured they'd just go to their last party there and see what it was like, and if they didn't feel it, they wouldn't sign the bid card. They ended up loving it!!
If you still decide not to do the rest of recruitment, definitely look into open recruitment.
All the best to you
I'm sure you'll find your way in the sea of sororities!
