Hey all,
I am a Phd student in Comparative Lit. at Penn State and I can only tell you that half of my incoming class is dropping out, and so am I. I have heard good things about science programs here but my ex , a PhD student at Computer Sciences also dropped out last year because they were so unfriendly, hostile and plain anti-social in his department. My gay friends do endure the horror of being bashed and are afraid to walk at night by themselves amongst the loud drunk jocks. It's heavily important to be into frats, partying and football here - academics come next. Everybody seems to be married and have a morgage. No racial/gender/cultural diversity. It's very rural and you are in the middle of nowhere. No real transportation to major cities, only an overpriced bus called Chinatown bus - imagine the conditions of that. Don't get fooled with the idea you can go to NYC all the time - only if you have a car and 8 hours to spend in a roundtrip. If you want diversity and cultural stimuli, do NOT come here, you'll not find it. Undergrds seem to love it but for grads it's a sad, isolated life with bad cold weather for 6 out of 9 school months.
hope it helped!
