According to Goodbye! Good Men, Mt. Saint Mary's is one of the most orthodox and non-gay seminaries in the U.S.
It's not quite as rosey as it seems. I have a very orthodox friend who just dropped out of seminary (the Mount) because of the overbearing homosexuality that is there(shower games that are just overlooked by the formation team; nightly visitations and sexual favors). He is discerning going elsewhere!
