Sticky rushing situation...should I try to make contact?

[jberks]

So currently I'm rushing and have been to 5 houses and have gotten a bid from one of them. There is this one house that I really want to rush since I know several people that have been in the house recently (graduated several years ago) and it seems like the one with exactly what I'm looking for (top academics, people in my prospective major, pretty social, good reputation) but I haven't heard anything from them. I went to the house during the university's greek orientation day with some friends and had a basic tour and chatted with the rush chairs (one of which went to my high school). Since then, the friends I was there with have gone to some rush events and signed early. Whenever I brought up that I wanted to rush the house they hinted, that they weren't comfortable just inviting someone since they're new and kind of just dropped the subject. I gave it some time (1.5 months) and I sent the rush chair a message on fb last week seeing if I could come out sometime but he still hasn't responded to me.

Should try to contact them again? If so, how? Continue to wait? Or should I take it as I'm being ignored?

Sidenote: I'm not "best friends" with these guys or anything. I knew of, and talked to the rush chair maybe once during high school and the others are basic friends that I would chat up in class and go to lunch with, nothing major.
