Federal Reserve Bank of New York (free tour)

Last week my children and I visited the FRBNY. It was a great tour and free.
They took us 50 feet below sea level to see the actual gold stored in the vault.
The FRBNY stores more gold than anywhere else in the world. My children
were able to touch it. They have an area with a guided tour explaining everything
to you. You must go online to make reservations ahead of time.  I would suggest
ages 10 and up.
