I can't speak to Boston, but in the couple college towns I've lived in, it really depends on where you go... there were certainly plenty of places where so-called townies frequented way more than the students, even in towns were the seasonal student population dwarfs the local one.

And before anybody jumps on you, I fully agree with the sentiment, college students in party mode can be extremely annoying to deal with if you aren't in the same mindset.

6th Street in Austin is a really good example of this phenomenon.
