He has loved his years at UC, and their co-op structure is tops. I think if he hadn't done his undergrad at UC, he would be going there for his MArch. Even though the undergrad and grad faculty is completely different, he has been hearing from his contacts from his co-op jobs is to get his Master's from a different institution. I'll check with S for more input.
UC has done tremendous things to improve their campus in recent years, with a focus on the campus architecture. See:
Power of Place, University of Cincinnati Magazine, November 2007
S has mentioned Columbia, and I'll pass along MIT and Cornell. Thanks.
