American Wish List

I decided that instead of just thinking things in my head, I would "write" down a list of places in America that I'd one day like to visit. I'm a bit of a nerd, so many of these places are educational. This list is in no particular order, and I reserve the right to edit it many times over.

1. Grand Canyon
2. Alcatraz
3. Washington DC- all the presidential monuments and such, including the White House
4. Smithsonian museums
5. Ellis Island
6. Statue of Liberty
7. various Civil War historical places- homes, battlefields, museums
8. Hawaii- Pearl Harbor, great beaches, volcanoes
9. Mount Rushmore
10. Williamsburg
11. weird and strange mueums
12. supposedly haunted places
13. Niagra Falls
14. Wyoming or Montana- the great expanse of land
15. homes of historical or otherwise famous and notorious people

For now, that's all I can think of. I know I've mentioned several places, if just to myself, over time.
Any suggestions for must-sees?
