Josh, I also just emailed you back but will also post here. Saturday January 5 and Sunday Juanuary 6 (1-4 pm either day) are both available and my contact at the Library has reserved both days for us. We need to pick one day and let her know by Friday so she can release the reservation on whichever day we do not want.
Looking at the Doodle results so far, Saturday would seem to be the day when the most people can attend.
