<p>Some great suggestions - I also suggest:
The Whiffenpoofs usually have a concert Parent’s Weekend along with an female group (who’s name eludes me at the moment). See them at least one time. There are other a cappella groups performing that weekend as well and they are poorly publicized - you may be able to get some details from other parents.
If you haven’t taken a tour, see the campus with a student guide. This is some of the most beautiful architecture in the country.</p>
