My sister and I (both 21) were traveling a long distance, and wanted to stop at this museum to look around before starting driving again! We were VERY impressed. We are from Ohio, so it was very informational, although we more came to look around instead of to learn (but we still did!). The exhibits are very nice and the museum is well kept up. We had to quickly walk through the 9/11 exhibit and couldn't spend a long time in that area because we accidentally used all of our time in other areas, but it seemed very impressive. We spent about 1.5 hours there and we would love to go back and see the things we missed. Highly recommended to just look around at cool things (from dinosaurs, to Native Americans, to wildlife, etc!) or to learn more about New York. Cost is nothing, but donations are appreciated.
