Sorry... but I'm an SR-71 fanboi. I will now infect you with my disease. Don't worry, it's (mostly) painless.
You don't have much a chance, considering I actually saw in SR-71 up close and personal, one that had been given to the Smithsonian Air and Space Museum. They, like most museums, don't have room to display all their stuff. The Smithsonian's stuff is rather bigger than others, though, and flies a lot of the time, so they have a hanger out by BWI (I think, it was a long time ago), with a good deal of misc. aircraft bits and some whole planes.
A friend of a friend's parent (I was perhaps 10 at the time) was a curator there and helped with restoration work, and got a few of us wee little munchkins a chance to visit. They had an SR-71 in mint condition there, which was probably the most intact of the stuff in the hanger. You could walk up to it, under it, touch it. The cockpit was a mess, a lot of the stuff was still classified back then (this would have been early 1990s) and had been torn out, but you could get down under it and stare into the recon camera lenses. I remember that very clearly.
The star of the place for me was a FW-190D partially restored, and they also had a B-24 that was in pieces, a F-5E Tiger II that was in need of major work to the engine nacelles and tail, a skeletal MiG-17, an engine from an ME-262, a TBM-1 Avenger they had just gotten that had been submerged in the Salton Sea for too long, and they were working on a replica A6M2 Zero (not sure of the specific model).
