I love the natural history museum so much. I spend hours here every time I go, and I still find something new to learn each time. The only suggestion I have is to have more events featuring talks from the curators, researchers, and other scientists who work for the museum. Maybe even tours of off-exhibit collections. (Or, if this is something they already do, maybe a little more advertising is in order!) I personally am very interested in the off-exhibit portion of the museum's insect collection, but that's just me. :)
