Apparently you can't play it as an embed in Facebook, either.
One thing I should mention that I don't think was covered here about DC. There are two Air and Space Museums, and they're both great, but the one out near Dulles Airport is probably the bigger attraction these days. That's the one that just added the Discovery shuttle, houses the Enola Gay, and a pretty rad SR-71 Blackbird (among many other planes). It's pretty fantastic. It's one of the few museums in the area that costs something, but it's really just a parking fee of $12 (meant to discourage people from parking there for the airport or commuting).
Anyway, if you have questions about the museums in DC (of which there are plenty and almost all free) then feel free to ask...and I'll ask my wife

Or my brother in law who volunteered at the Smithsonian for a while.
