A little hidden treasure in DC is this library/museum/garden all stuck out by the side of the road near the FDR Memorial. It's called the Annual Library and is a collection of 100 plots that are all laden with annual plants, planted fresh each year. There is this sign, the plants, and a waterproof boxes with crappy xeroxes of what may have been a nice brochure. I was just tickled becase, well, it's a library.
