I love museums!  I want to visit a museum soon, which one should I plan a trip to go visit?
I love museums. Its nice to have a place that conserves cultural, artisitc, historical, or scientific objects of importance. I would suggest going to one that you have an interest in.
I personally love dinosaurs and ancient history like that.  Any suggestions for a museum like that?
I would suggest contacting your local museum. There are thousands of local museums but the largest ones of course are in the larger cities.
Are there a lot of museums in the United States?
There are many famous museums in the United States. There is the Smithsonian in Washington DC and the Metropolitan Museum of Art in New York City.
