The wonderful Holiday Train Show at the New York Botanic Garden opens this Saturday, and Gothamist urges anyone with a passing interest in NYC architecture to head up to the Bronx to see it. We went last year, and it was absolutely magical: The Guggenheim made out of huge mushrooms! The Brooklyn Bridge carefully constructed from twigs - with trains zipping on it! The lions outside of the New York Public Library! The NY Times' Ink column looks at the creation of buildings and bridges, which has Yankee Stadium as a new addition this year, and there's a great quote from tPaul Busse, the landscape architect who builds the models: "Every year, we take a ride into Manhattan. But after working with our buildings, the real thing can almost be a letdown."

Here's information about hours and ticket prices; it's an easy trip, either by subway or Metro-North.
