It wasn’t a cheap ticket by any count, especially for a museum that hasn’t changed it’s core exhibits in the last double digit decades but it was a sight to behold 
thus worth the price of entry. The Origami Holiday Tree at the American Museum of Natural History. I didn’t count them, but word has it that more than 500 paper creatures adorn
the plastic tree. [Which I am coming to believe in after years of scoffing].
The creatures all relate to exhibits in the Museum. While searching for the tree we passed through old halls of old stuffed animals; spaces not anticipating the modern use of double wide strollers and parents with backpacks so full, they could survive for a week among the wild animals.
