I know it was weeks ago (three, to be precise), but I figured I would post about attending YCT's Yemei Iyun, nevertheless. It was their fifth annual such event, this now being my third consecutively-attended (including having attended it last year).
For me, the best sessions were those presented by Rabbi Aryeh Klapper (with whom I just spent this past shabbas up in Boston). He presented four sessions: "Writing Modern Midrash," "What is the Purpose of Animal Sacrifice?", "So Long, But Thanks For the Fish: A New Reading of the Jonah Story," and "Maimonides and Messianism." Yes, there were others I attended and from which I benefited, such as Rivka Kahan's "Understanding the Enigmatic 'Hatan Damim' Episode of Ch. 4 of Exodus" which has always been a puzzling text to me (and many others, I'm sure).
Whenever the lectures get uploaded [here], they are definitely worth a listen.
