Our son and daughter-in-law met two other couples there who had children of about the same age, making for a nice tableau.
Most of the light displays featured zoo animals, naturally, including the following.
OK, this last might have been of questionable authenticity.
For the most part, I took these shots by underexposing them by one full f-stop. Not only did that help to keep the background black, it also allowed me to take the shots at a lower ISO for a given shutter speed.
I also took some shots that incorporated some of the lights-wrapped, snow-clad trees.
Of course, zoos are about animals and there were some in the enclosed buildings, which also gave us the opportunity to warm up a little on a very cold night. The one interesting animal photo I got was of four monkeys huddled together against the cold who had entwined their tails.
