I guess that wasn't too clear.
Let's say I wanted to go to a Pi Phi house in my homestate, just to see it. Like, the USC house. My brother was a Greek at USC but that's irrelevant. Anyway, would it be "proper" to visit the Pi Phi house without notification? We would let them know that we were Pi Phis in our own special way

of course. Or would it be better to contact the chapter president?
Am I making any sense yet? It doesn't seem like it....hehe.
