I'm currently scheduled to be in Boston on Tuesday and Wednesday December 4
and 5, so Thursday and Friday December 6 and 7 are currently my preferred
choice for a f2f meeting. (I will be in Europe the following week, so that
won't work for me.)
Thursday and Friday of the preceding week (November 29 and 30) would also work
for me. There's a small chance that my schedule for the first week in December
will be changed, but I will certainly be available in Boston for two to three
days that week. The schedule will be firmed up next week.
