By the way, if you haven’t made plans to go to the train exhibit at the US Botanical Gardens, do it!  This free exhibit is absolutely fabulous- and the whole place is exquisitely decorated for the holidays!  You’ll find a photo op around every corner.  Go early- they open at 10:00 and tend to get crowded as the day goes on, although we got lucky and the place was only reasonably busy while we were there.
