Aussie,
I'm glad that you're considering Greek Life. There's really no better way to get aquainted with the US. We currently have an international member from Japan in our chapter. He was with us 2 semesters, won this prestigious award thing and got to go away on some diplomatic mission for Japan until next Spring. I remember driving him to a party during Rush and he kept telling me how he liked beer
While beer is in plentiful supply there is so much more as I think he and probably you will find out.
Good luck!
