It was really windy for our last field trip and neither of us wanted to spend all day outside so we did the shorter Federal Triangle walk a little out of order since we're really in the 1910s. This walk is very compact and heavy on federal buildings, obviously. There was some information about what was in the area before the redevelopment. I'd have preferred more, but overall the balance was right for what the walk was trying to do.
We also tried eating in the Ronald Reagan building which turned out to be surprisingly affordable. The food court there has more and better choices now than Union Station and, if anything, was less expensive. I'm going to start recommending that to people looking for a place to eat when they've been in the Natural History or American History museums.
And since there was time and since it was close and indoors, we also took a tour of the Bureau of Engraving and Printing (the main building was built in 1914 so I guess it sort of counts even though it really doesn't have anything to do with the city). It was interesting.
