I strongly suggest going to the Morris Museum in Morristown, New Jersey.
It houses the Guinness Collection and displays it proudly.  An entire
wing was built onto the museum _just_ for the Guinness Collection!  It's
not that far from New York City, and well worth renting a car to visit.
Here's a link for the museum:
