November is fully booked.  There is still one 4th from the top spot available in December (all the others are booked).  The next top spot opening is in February (and there is at least one top spot available thereafter).  January still has some 3rd and 4th spots available, but the top two spots are booked on both sides.  E-mail me (bleiter-at-uchicago-dot-edu) if you're interested.  In general top spots (except in the summer) tend to get booked three months or more in advance.
