(Going to burn for this, as I am a Penn State student...)
I live in Pittsburgh, and I think Pitt is an amazing college campus. it blends so seamlessly into the downtown cultural areas. I sometime kick myself for not wanting to stay close to home, but my parents were going to make me commute, so I opted for Penn State
Since I'm from NC,I have to say you can't go wrong with either Duke or UNC's campuses. Also,I heard ELON had won an award for most beautiful college campus by one of the rags too.
