There are monuments and museums to women's suffrage in upstate NY, IIRC near Geneva on the Finger Lakes.

For the history of the atomic bomb, you can visit the museum and "log house" in Los Alamos. This requirers flying into Albuquerque (drive via the Turquoise Trail in at least one direction) or Santa Fe and renting a car. Near the airport in Albuquerque, there's a museum focusing on the atomic bomb on an air force base. [You must make advance arrangements to visit so that your car will be let in the gate to the base. They inspect vehicles too.] Also nearby, there's the Tamayra (spelling?) Hyatt on an Indian reservation (with casino, but not near the hotel) which has a museum devoted to the local Indians, staffed with hotel employees from the tribe that owns the place.

Minnesota has a Museum of Minnesota History in St. Paul and a network of historical sites, all under the Minnesota Historical Society. Many of these places and frequent special programs and exhibits tell the story of American Indians in this part of the USA.

There's a museum of black history (not sure the exact name) down the road from the St Regis in Atlanta Buckhead. In the uptown area of Atlanta, you can visit the apartment (about a block from the Hyatt Midtown) where Margaret Mitchell lived when she wrote Gone with the Wind.

Birmingham is good for various museums of black history.

Don't forget the Vietnam War Memorial (wall) in Washington DC.

I don't know whether they're still running, but there were Katrina tours of New Orleans Ninth Ward.
