This is the old Smithsonian where I spent untold hours wandering and wondering as a child in the fifties. With the dim lighting, brief simple typed labels, and best of all, no "docents"...errr that would be guides, we were free to politely wander as we would. Suits of armor, swords, pikes, halbards, matchlocks, wheel locks, ornate bejeweled weapons of royalty, intricate iron machinery, airplanes, tiller steered autos, tanks, artillery, all the wonders of the world ours for a few hours. Life was good then.
Now that space probably has less than 5% of the exhibits, overwhelmed with pc graphics and text walls. Multimedia, short attention span theater.
