May I suggest a couple of activities for those who are going to the
conference, if you have time:

The Pabst Theater is one of the most beautiful theaters in the U.S.,
with superb acoustics. They offer tours Saturdays at noon:

Bob Paquette's microphone collection is far from downtown, but it is the
best collection I have seen of pre-WWII mics. Call first:

Enjoy!
