You’re welcome and yes, a lot of students drink here. I have no idea how many students drink at Wisconsin (although some surely do), but I wouldn’t solely not come to Indiana based on that. Actually, I just found these links on google, and Wisconsin is above Indiana in terms of drinking and partying according to these sources.
