Danbury Library is turning 150 and a celebration is planned for tonight.  Local food trucks will gather at Library Plaza as live music and other entertainment offerings happen.  There will be magic tricks, face painting and an arts and crafts station.  The Friends of the Library book sale table will also be set up.  The first 150 attendees will receive a free cupcake.  The event is 5pm to 7pm, but will be cancelled if there is rain.
