Disagree with post # 21’s statement about 50% of town-college.
The influence of UW on Madison is huge, along with having all that goes with being the state Capitol. They are likely the one-two in town. The mile or so up/down (hills)from campus to Capitol on State St. made it easy for students to participate in the sit in protests against what the state was doing several years ago. Oscar Mayer- a distant third eons ago.
In a medium to large city a lesser percentage can still mean a huge impact. Such as mentioned about Boston above. One can also interpret a college town as having great nearby places, not just the on campus sites.
