Here's my take: You know you're going to be on campus every weekday and some weekends. Class starts as early as 8:00. I'm not sure what a "social life" is in medical school but if it's going to concerts, having a drink at a bar, reading a book in a coffee shop, my thinking is that most of those can be done close to the school and those that can't will be much more infrequent than attending class. Basically, make the commute into Milwaukee when you want to see the Bucks play unless your priority is something other than medicine then make attending lecture and studying your secondary consideration and live downtown.
