I don't mean this to come off as rude, but at 29, you have no possibility of receiving a bid at Arizona. There really is not an easy way to say that. It may be the west, but we have one of the most competitive recruitments outside of the SEC. Greek life is extremely traditional and so is the age range of the members.
Also all chapters have a live-in requirement. Would you really want to spend two years living with the daily drama of a bunch of 19 and 20 year olds? Trust me. It's hard enough when you're the same age range!
