I had 2 Rho Chis (yes, that was waaay back when), one was a Tri Delta and for the life of me I can remember what group the other was from. They were really no help to me whatsoever, but the Rho Chi who was of tremendous help to me was an AGD and it was hard b/c I had fell in love with AGD during recruitment and they had cut me right before pref, that Rho Chi, helped me see it through and also help me see how outstanding Tri Sigma was (and still is
).
