Bro,
Phi Psi, and many other GLOs, derive their alcohol policies from the
FIPG.
I just IMed our ED and asked him, "how closely do our risk management policies follow the FIPG's
Risk Management Manual?"
He answered, "to the 'T'"
As for deciding to go dry, I think that its great you decided on your own. Its easy to make that decision now. If you were to have a wet house for a few years, and then decide to go dry, there would be much internal resistance.
Alumni opposed to going dry will get over it, or might be alumni that you don't need around the house until they do.
