In response to the Denison comments, I’m a recent grad and can speak to the drinking there. Yes, there is quite a lot of drinking, but Denison has really changed over the years. I’d say about 1/3 of the student body drinks heavily, 1/3 moderately, and 1/3 very little to not at all. Definitely no more drinking than other similar schools, such as Kenyon. I didn’t drink at all my first year and I have friends who didn’t drink at all during their entire time at Denison without ever feeling pressured or like their social life was lacking, though I’m sure it depends somewhat on your friends.
Someone said that they have stopped recommending Denison due to the health hazards relating to drinking. Definitely not my experience on campus.
