The seminars run by the Institute for Humane Studies are a lot of fun - at least they were 20 years ago when I did one. I suspect they're even better now.
The seminars provide an introduction to classical liberal thought across a range of disciplines. In my experience, the students were at least as much fun as the faculty. When I did it there were people from all different perspectives within, and in the neighborhood, of the classical liberal perspective, ranging from anarcho-capitalists to Randroids to conservatives to sensitive, wonderful, clear-thinking and nearly always correct people like yours truly. :)
Well worth doing, if an experience like this appeals to you.
I even met someone I dated a few times.
Who was my favorite student this term?
