Most visitor will say 80% or better, however I guess I didn't research the museum enough. Some photos showed some dinosaurs that that gave the impression the museum has a natural history, bad thought. The dinosaurs are part of the Colossal Fossil exhibit, which are a T-Rex, Triceratop and a flying Nyctosaur-a Night Lizard. Along one wall are a head of dinosaurs in a swamp setting.
On e exhibit that caught my intersest was the Elihu Thoms0n-from Manchester,England-which is about the Thesater of Electrial Science. another site is the Natural Mysteries . Another exhibit a nunmber of model boats'/ships from a 2500 BC Egyptian Sea Going ship up to a 1929 Hi Esm yacth. Also is a small exhibit of model steam driven trains. Not far away are steam engines of the early 1800's.
The one exhibit nor expected was The New England Habitate, which is subtitled' Windows into the Natural World'. The habitats exhibits are-Black Bears, White-tailed deer, Shore Birds, American Moose, Beavers & Sea Birds. Each exhibit has a small information sign that tells where the animals/birds came from.
The museum's eatery is the Riverview Cafe, which serves a different menu each day. I would rate the cafe a 'B'. The food is a bit bland. however the seletion will take the hunger pains away. The cafe faces south at the Charles Rivr.
The museum is three levels, with the lobby being the middle lavel. At admissions each visitor will receive a map of all three levels. The map will show all exhibita as well as the restrooms-two on each level & handcappied- the Riverview Cafe, museum's gift shop & all stairceses. If I had studied the map more closefully I would have done a better receive al more exhibits.
Parking.
The museum's garage is three levels. To pay for parking, stop at admissions, pay for parking. A visitor will receive a pay stub which they will incert into a gate machine, a gate will open up and drive out.
Don't take what reviews say, go with an open mind. A lengthly visit is highly recommended.
