The three things you need to know today in New York: Wed December 20

1. A new ice-skating exhibit opens at the Museum of the City of New York today. It goes back to the 1800s to give you the sport’s history. 

2. Watch 420 The Musical at Kraine Theater tonight. The Christmas comedy gives a portion of proceeds to charity and serves free snacks. 

3. Attend Voices in the Pavement, Street Art and Gender Equity. It’s a class at The Commons that covers famous street artists from New York’s history.
