Campus should be pretty quiet on the 21st (the last commencement ceremony is the 20th), so if I were you, I'd call the Admissions Office and let them know you're coming for a visit-maybe you can get a tour? Even if you don't want to meet with Dean Hall, at least they'll have your name as someone with a demonstrated interest in the school. You should definitely make some time for grabbing a beer at the Terrace and taking in the gorgeous view. I'd also suggest State St. (of course) and trying a slice of mac 'n cheese pizza at Ian's (on Frances St.). I'm finishing up my undergrad here, so if you have any other questions about campus/Madison, let me know!
