Nathan says he is open to change his mind about the negative impression he has of fraternities generally. So Colgate, with its 5 fraternities would not necessarily be a deal breaker.
As you see below, freshmen and sophomores are not eligible to live in Greek houses (there are 3 sororities) while there are 9 “interest-based housing units” alongside the general/other upperclassmen housing options available to all.

I hope you visit Colgate soon and see what’s so special about this unique LAC for yourself!
