When I attended, nearly 50 years ago, I was studying architecture. I recalled reading that (at that time) Iowa State was only 1 of 5 major universities in the land still following an architectural plan. Interestingly, I believe it still is. At least that's what I can glean from Google street view. If so, that is simply incredible. No, I can't recall the other 4, but it sure would be interesting to know.
