Separated at birth: The Smithsonian's National Air and Space Museum and The United States Army Aviation Museum. Air and Space being the original.
Tulsa Race Riots of 1921: Who pays? I don't think Oklahoma Gov. Frank Keating's pledge to fundraise for a memorial/museum will suffice as a remedy -- or cut much mustard with survivors and their families. (Background info here.)
If anyone is (or will be) in New York and have nothing else planned for this evening, may I suggest a trip to the Brooklyn Museum of Art. BMA is free on every first saturday of the month (from 5 PM - 11 PM). Today's theme for the evening entertainment revolves around their special exhibition, Hip-Hop Nation: Roots, Rhymes and Rage. There will be an outdoor dance party (at the BMA parking lot) starting at 9 PM featuring samples from 20 years of Hip-Hop music. You can also walk through their current exhibitions, of which the Robots and Space Toys seems promising.
