Fun Site Alert! - The International Spy Museum
IMO— the International Spy Museum in DC might be a good idea for, I think, 9 and older. (I loved it!) VERY Interactive stuff like the laser traverse activity in the pics but, also, you get to decode cyphers, test your memory, etc. (and museums can be overwhelming i know). Anyway, let me know if you have any questions about my trip there—and if you go, would love to hear your thoughts!
