Attractions of the Smithsonian Institution

I've thought about all those things before. I can explain why I didn't do them, though you may disagree. I didn't accept African American for both museums with African in the title because one of those museums is about art from Africa, not art by African Americans. And the other is about the history and culture of African Americans, not of Africans. Different things. Air & Space I thought was so well known (as evinced by the fact that 100% have guessed it so far) that I wanted to leave Udvar-Hazy as a separate answer for those that knew about it. If they were the same answer then Udvar-Hazy would also be at 100% yet not many people know of it. The Hirschorn is a good idea, I think I will add some type-ins for it. Though there is also a Washington Museum of Modern Art which is not part of the Smithsonian... but not a big deal and you're right this quiz could stand to be a bit easier.

you're welcome. :)

Good question about the Ripley Center. I got my list from the Smithsonian's own website and didn't see it before but now when I go there I can see info about it. Never heard of the festival, is that a permanent attraction?

Actually if you go to the website and look at the left column where they list all the museums and attraction the Ripley Center is not there, even though I found a page on it by googling. Not sure why. That's why I missed it.
