Hi! It appears that we have 2 Brooklyn, NY in our database and you ended up with the country hamlet. We'll be removing the latter from our system shortly.
In the meantime, you can go to the famous Brooklyn @ http://www.travelmuse.com/destinations/US/NY/047/00-brooklyn and click "Save to Trip" button to add it to your trip.
We apologize for the inconvenience and appreciate your feedback!
Thank you for using TravelMuse!
